Grand Avenue Central Maintenance Facility

On the level above the Grand Avenue Bus Depot is the Grand Avenue Central Maintenance Facility, which can do repairs, overhauls, and painting of buses. It can also handle compressed natural gas (CNG) buses, which are not allowed in the bus depot below for safety reasons. The facility has storage of parts galore, two huge paint booths, and numerous bays for repairing buses. Also, at the time I was there, it had a vintage bus in for repair, which was really cool to see. There were also all these cool looking parts for the buses, none of which I could identify.

Grand Avenue Bus Depot

I toured the New York MTA’s Grand Avenue Bus Depot with the New York Transit Museum. The depot is relatively new, which is evident when you are inside. I don’t know much about bus depot design, but I was astounded by the amount of ventilation in the building. Considering the number of vehicles going and in and out every day, the ventilation is needed, but still I was surprised by the amount of it. The bus depot occupies the first level of this huge building, and the second level holds the Central Maintenance facility. They are considered to be different facilities. The bus depot is, well, a depot, or parking area for when the buses are not in use. The depot also where regular maintenance is performed and everyday activities like fueling, money removal, and washing.

I asked the facility manager what this garage style door was for. He looked at it and me and said he had never been asked that and wasn't actually sure. Leave it to me to be able to stump people.

Confession: Other people in the group asked the depot manager to please let us go through bus wash, so he granted their wishes, and we all boarded a bus and went through a wash.

The ceilings and walls were almost completely filled with ventilation ducts, pipes, and conduits.

One of my favorite parts of the tour was learning that they vacuum money out of the fare box. MTA buses only accept coin and not bills. They hook up a hose to outlet at the bottom of the fare box, and the money is vacuumed out to secure boxes where it falls into bags or some other movable containers. The staff of the facility never touches the money. Then the money is removed from the boxes on a regular basis by armed staff. I think it is because I have a B.S. in chemical engineering that I found this so fascinating. We learned about pipes and other conduits and pump design for fluids. Coins are obviously not fluids. I am intrigued by the design that would be needed by items that are going to bounce around and not flow the way a fluid does. Also the pressure needed to pull coins out must be interesting.

The outlet at the bottom of the fare box is where a hose is inserted to vacuum out the money. They vacuum the money to a secure box.

Cabrillo National Monument

While in Sand Diego, I visited Cabrillo National Monument. Actually I visited it twice. I went in the morning, and the entire area was covered with thick fog. I explored the tidal pool area and met some cute crabs, limpets, and snails. I then went to the peak area and tried to view San Diego underneath the clouds. It was kind of amazing to be on a peak about 400 feet above the ocean and look at a giant fog encompassing almost everything below. I then came back in the afternoon and was finally able to get some good views.

I was in San Diego recently for a conference, and I was able to take a few days to wander around and see a little bit of the city. A few blog posts to come with photos, but here are some from just around town.

I enjoyed my visit to San Juan, Puerto Rico and just need to post a few more photos from my trip. Viejo San Juan really is a lovely area to just walk around and absorb the atmosphere.

Castillo San Cristobal

On my last day in Puerto Rico, I explored Castillo San Cristobal, a fort built by the Spanish to protect San Juan from attack by land. It was built between 1634 and 1790, and then the U.S. added a few concrete additions during World War II. The fort is huge and has a series of tunnels. Some of these tunnels are huge, connecting the different levels and areas of the fort, and were designed to have defensive explosives. Some of the tunnels are really small, and you have to stoop to move through them. If you ever get a chance to visit, try to get one of the ranger guided tours of the tunnels. Those tours besides being very informative, let you go inside some of the really small tunnels in which you normally aren’t allowed.

Cueva Ventana

I got to visit Cueva Ventana (Window Cave) today in Arecibo, Puerto Rico. The tour starts by walking by Pee Wee Cave, which only meets the bare minimum requirements of a cave.  You don’t go in. There is no point or room really. There is a short walk through the forest, which when I visited meant getting to see among other things a bunch of giant snails on the trees. Then you walk through cave number two, which I don’t think they actually named. The middle portion of this cave is, well, cavernous, with huge ceilings and wide walls. However the walk through it is fairly short. Then you walk down an extremely steep path to get to the actual Cueva Ventana. There are bats living in there among the limestone columns. At the end of the cave is the Ventana. It has amazing views of the Arecibo River valley. The valley is gorgeous, and you can see the mountains beyond. The tour is worth the view alone. However the caves are really neat to see also, and I love bats, so getting to hear and see them was also a highlight. Sadly while there, you can see vandalism from years past, but tourism is now helping to support security and clean up for the site.

Viejo San Juan’s Colorful Buildings

I love buildings that are painted bright colors. They grab you and make you look at them. They look fun, festive, and alive. The Caribbean is famous for its colorful buildings, and Viejo San Juan has its share. Here are a few of the colorful buildings I saw in Viejo San Juan that I really liked.

Viejo San Juan

It wasn’t until I walked around Viejo (Old) San Juan, especially the perimeter of it, that I realized how it really is a walled city. El Morro guards the entrance to the bay, but the fortifications encircles the entirety of the old city. One of the few ways, and the historic way, from the sea level to the city is through La Puerta de San Juan. Walking through the La Puerta, you realize the fortification is serious fortification, as La Puerta is almost a tunnel in terms of the distance you must walk to go from the sea side to the city side. The fortification is truly impressive with the wall thickness and garitas and small openings for guards to stand ready. One modern day bonus of the fortification is that it must help protect Viejo San Juan from any hurricane storm surge. There is a promenade that follows the wall from its beginning on the bay side and ends on the ocean side of El Morro. It gives spectacular views of the fort and the water as well.

Iguana

While touring El Morro, I discovered that it is guarded by a platoon of iguanas. I will assume that is what they are all doing there. That, and most of them seem to be there because they know that is where there is a lot of tourists, and the iguanas like to have their photos taken. Iguanas are hams. One was posing on the top level. I took a few photos, walked away to take photos of the fort, and walked back. The iguana had moved closer to the edge and where the people were. I kneeled down and got out my macro lens, and the iguana obliged by posing to make sure its best side was shown while I took photos for several minutes. Now, I only do what the iguana clearly wanted and post its photos.
