I have been in Juneau for several days now, and I have had a chance to walk around historic and not completely historic downtown quite a bit. Juneau reminds me of many older cities where they still have some of the historic buildings, which in many cases have been restored and repurposed, and they have new buildings mixed in with the old ones. There is a Main Street, but the main street seems to be more Franklin Street, although with so many shops closed because of lack of cruises, downtown is slightly not normal. However because there are no cruise ships, Juneau is easy and pleasant to walk around, as in not crowded, and you can actually stand on the docks and look across the water to Douglas Island. Near downtown, Juneau has a seawalk, which is nice walk to view the water and tidal flats. Ravens are everywhere, but bald eagles are not as easily sighted.
