When visiting anywhere in Eastern Connecticut or Western Rhode Island the trip cannot be considered complete without at least a 1/2 day spent at the Mystic Seaport in Mystic, CT. Essentially a world-class museam of classic ships and incredible historical data that, along with wandering through the various boats within the museum, takes you right back to what the sailors, travellers, and slaves must have felt during their voyages to, from, and around New England during the days of colonization.
The weather was great when we went to Bluff Point, which was a key factor as our plan was to spend spend some of the afternoon walking! There were a few people here and there, some walking with their children or dog, some cycling and some fishing. The walk we did took around 30 - 40 minutes in each direction, on quite level ground and so it was good place to take our friends' two children for a day out.
This was a very in depth museum. The land-based museum had a ton of naval memorabilia and interactive stations. The submarine itself was very informative. We had trouble with our audio speakers, though. The submarine is only for the physically fit. I don't think an obese person would be able to fit through many of the doorways.
