The main reason I attend Nationals is to see the skating . Over the years I realized that visiting each of the cities hosting Nationals might be the only opportunity I have to see the sights of the area. I've been to Mall of America in Minneapolis, the CNN Center in Atlanta, St. Louis Arch in St. Louis, etc. Boston has so many sights that it is staggering. I mean, golly I do want to see the skating, and there are just so many places to explore.
Here's how I think I'm going to see the sights! Boston offers trolley tours where you can get off and back on at many different places. The driver gives you a running narrative about the area and places you will be visiting. If the weather is awful, I may just ride around for the 2+ hours and listen to the commentary. The areas that most interest me are Paul Revere's home, Old North Church - the historical stuff. From what I've read the streets are very narrow, so the trolleys don't take you right up to the door - there is a certain amount of walking involved - but it isn't a lot of walking.
Anyway, if you think you might enjoy this kind of thing look up Boston trolleys - there are quite a few companies. The one I will probably use is Old Town Trolley because they are supposed to be heated and seem to have the biggest fleet so you don't wait as long to hop back on if you've gotten off to see something.
Just throwing this out for anyone interested.
