The Constitution Inn is fabulous - attached the YMCA whereby guests get to attend classes and uuse the Pool for free. I got a shuttle ride (in the dark) to a nearby building on the historic site and others on the bus were kind enough to tell me how to shortcut it to the Inn. Then I hadn't eaten so found, in the dark, the Tavern on the Wharf which was like a beacon in the dark.
The skyline of the lights and shapes of Boston reminded me of Baltimore and the owner came over to chat as they weren't busy, and said it was similar to Phili as well . I didn't get that, but now i do, as Phili has a shipyard, and Boston has the USS Consitution. I got a hop on hoff off trolley ticket on Monday and the winter offers a ticket that can be used for 7 consecutive days, a really good deal. I went to Pilates on Monday night. On Tuesday I walked from the Inn to downtown Boston and the Appalachian trail office to get some ideas of where I could Thanksgiving dinner somewhere on the trail.  
Went to see the Cheers Bar (on my dad's recommendation). It is on the circuit for the Hop ON Hop Off bus and very popular. Another person got off at this stop, a woman from Kansas who was in the city while her husband was at a conference so she and I ate lunch together and got her to take some pics of me. Took this bus to Mass. Institute of Technology (MIT) just over the bridge into Cambridge. Another day I took the subway to MIT and walked to Harvard, about 2.5 miles away and soaked up the history and the ambience as well as had lunch at a vegetarian restaurant that I read about. It was underground so took some doing trying to find it. Interesting how accessible these iconic and historic institutions are.Got back to downtown Boston in the pouring rain to where the free shuttle was for that took people to the Navy Shipyard, where my lodgings were.   After a week at the Inn, I wanted to stay at the Hostel but they were completely booked until Sunday so on Friday I took the bus to Hyannis for the weekend.
