Venice

Posted on February 10, 2020 by geek

I arrived in Venice, Italy for the start of my vacation in Italy and Croatia. After my plane landed at Marco Polo Venice airport, we were taken by van to essentially the other side fo the airport by the tour group with which we are traveling. From there, we boarded a small boat that is one of many that operate as water taxis. The boat took us directly to our hotel. Not a bad way to travel.

I am completely jet-lagged, but I walked around a bit to try to stay awake and get more tired, so I can get a really good night’s sleep tonight. I once read that you have not really been to Venice, until you have gotten lost there. I did not in fact get lost today, but there were a couple of times where I could have easily gotten lost. Venice is a series of twisting, narrow and wide, alleys and streets that intersect constantly in non-uniform manners. However, it is lovely here and so unique.

Richmond Canal Walk

Posted on October 12, 2019 by geek

I am continuing my quest to see all the state capitols. I am in Richmond this weekend to see the Virginia state capitol. However, today, I just wandered around. I spent most of the day walking along and near the Richmond canal walk. Richmond has a couple of disjointed canal that were originally part of a large system so that ships could avoid the James River rapids. The canal walk is lovely. The original building of the canal and the restoration of it are impressive engineering projects. They have restored much of the system, and you can even take a boat ride along part of it. [I did, and some of those photos are included.] Railroads and then highways were built alongside and on top of parts of the canal system. My tour guide on the boat ride noted that there is one part where you can see 18th century (the canal), 19th century (the railroad), and 20th century (the highway) transportation systems all in a single frame. I thought that was an interesting and insightful observation. The canal also is both inside and outside the Richmond flood wall, which is another impressive piece of engineering. A canal was built to bypass the James River rapids, and a wall was built to protect against James River floods.

“The Lowline” is hike and bike trail along an elevated railroad next to the canal.

Part of the canal is inside the Richmond flood wall, which has a gate seen here for boats to pass in and out of the flood wall.

The canal is below railroads and highways in parts.

Abandoned buildings are alongside the canal. This one has numerous original murals.

F.J. Horgan Water Treatment Plant

Posted on May 26, 2019 by geek

The F.J. Horgan Water Treatment Plant was one of my top two reasons for coming to Doors Open Toronto. Sadly, no wastewater treatment plants were open for the event, as I find them more interesting than water treatment plants. However, water treatment plants are still interesting. This plant was even more interesting than I initially thought it would be because I am fairly this is the first water treatment plant I have been to where they use ozone for the initial disinfectant. This is the second water treatment plant I have visited in Toronto. The first Doors Open Toronto I came to, I visited the absolutely magnificent R.C. Harris Water Treatment Plant. F.J. Horgan Water Treatment Plant is not as beautiful, but it is interesting none the less.

The plant’s water intake is from pipes in Lake Ontario over 2 km from shore. It is then pumped to the plant and then up from the pipes which are (I think) nine stories below the surface. The plant sits on cliffs high above the water surface. Ozone is added to the water. Ozone disinfects the water. The ozone is made at the treatment plant from liquid oxygen. Before the water leaves the tanks where is contacts ozone, sodium bisulfite is added to remove any left over ozone.

Coagulant is then added to the water. Coagulant causes certain ions and tiny particles to start to come together to make bigger particles, which are easier to filter out. The water is pumped to sediment filters. The filters have a lower sand layer topped with a carbon layer. The filter tanks are huge, but so are the pipes in the building.

This is a horrible photo because is taken through glass with wire lining, but that is water in the filter tanks. The filters are at the bottom, and I think blue plastic thing is the trough where the backwash goes when the unit is backwashed.

Another horrible photo taken through glass, but on the left side is an empty filter tank, and on the right side is a filter tank with water.

After the water has been cleaned, chlorine is added. The water has already been disinfected at this point, but a residual disinfectant is needed to kill any bacteria the water may encounter in the distribution system on its way to customers.

Sea of Cortez Cetaceans

Posted on January 2, 2019 by geek

First off, the reason why I am titling this post cetaceans, is that I can’t remember if they naturalists on the ship decided these were whales or dolphins. While on my ill-fated trip to Baja California, the ship passed cetaceans several times, and several times the cetaceans came to ride our bow wave. It was so fun to see them. I decided to post some of the better photos that I took. If anyone can identify which specific cetaceans these are, I will happily update my post. Also, in some of the up-close photos of them riding the ship’s bow wave, remora fish stuck onto the cetaceans are visible.

Snorkeling with Sea Lions

Posted on December 29, 2018 by geek

One of the things I was able to do while on my short cruise in the Sea of Cortez was to go snorkeling with sea lions. There is a small island, which is more of a large rock outcropping, were birds and sea lions live. The water beneath is filled with fish, otherwise why would the birds and sea lions be there. People are allowed to snorkel in the area, but they are not allowed to dive there. We were even required to wear a slightly inflated flotation vest to prevent us from diving. We were also warned that the sea lions are quite playful. They are known to like to gnaw on people, like a puppy might when playing. I got gnawed on at my wrist. Then either the same sea lion of another gnawed on my ankle and kept going right up to my thigh.

The sea lions are amazing to watch. They are so swift and fast. They are extremely hydrodynamic. They are cute and playful. Although the gnawing didn’t break the surface of my skin and didn’t hurt too much, I could have done without the gnawing.

These are not the best photos I have ever taken, but GoPros are only point and shoot. Still I though I would present some of the better ones.

Sacramento River Cruise

Posted on December 3, 2018 by geek

While exploring Sacramento, I decided a river cruise would be a great way to see the city, considering the city is on the banks of two rivers. A river cruise was definitely a lovely way to get a different perspective of the city. The cruise only went on the Sacramento River, as my guess is the American River is even more shallow than the Sacramento, which is only about 12 feet deep. The engineering highlights of the cruise were going under two different bridges, the I Street Bridge, which is a swing bridge, and the Tower Bridge, which is a vertical lift bridge. The cruise also went under a boring stationary bridge, the I-80 bridge. The cruise also passed by both the old and new water intake pumping stations, where river water is pumped to the water treatment plant.

Penobscot Narrows Bridge

Posted on August 9, 2018 by geek

While traveling though Maine, we drove over the Penobscot Narrows Bridge, which is a lovely cable-stayed bridge. Cable-stayed bridges are my favorite kind of bridges. I love their simple elegance and functionality. The Penobscot Narrows Bridge is unique in that it has an observatory on top of one of the pylons. Who would have thought to put an observatory on top of a pylon? Next to the bridge, you can also walk onto a small portion of the old Waldo-Hancock Bridge. The Waldo-Hancock Bridge was suspension bridge built in 1931. It ultimately had to be taken down due to heavy corrosion of the main cables. The Waldo-Hancock Bridge was replaced with the Penobscot Narrows Bridge in 2006.

A thunderstorm passed by right before we entered the pylon, so in the below photos taken from the observatory, there are some of out of focus areas. I waited until the storm passed before taking the photos, but the windows still had raindrops on the glass, so the photos are not completely clear.

Acadia National Park

Posted on August 8, 2018 by geek

While visiting Maine, we took a whirlwind trip though Acadia National Park. The park is spectacular. There are wonderful views from Cadillac Mountain and along the coast. While we were there, a fog rolled in and provided mysterious and obscured views. Based on the views, I have come to the realization that Maine’s coast is just a series of rock outcroppings.

Hudson River Valley by Train

Posted on June 27, 2018 by geek

I just got back from a very short trip to Albany, but the main reason I went to Albany was for the train ride up there. Amtrak has several train routes that go from New York City to Albany. I have taken two of these routes before, and I just love the view. I spend almost the entire time staring out the window at the gorgeous Hudson River, which can be seen during the vast majority of the ride. Below are a few photos I took on the route. The first six were taken on the train ride up to Albany as a storm was passing through and the sun was setting. The last three were taken on the way back down to New York City.

Regents Canal

Posted on May 27, 2018 by geek

I posted yesterday about my boat ride on along the Regents Canal from Camden Locks to Little Venice. Today I went for a very short walk along the same canal in the Camden Locks area. It really is a pretty area. It is also a very popular area. There were many people walking along the towpath, and there were also many people just hanging around the area.
