I spent one afternoon/evening in Mystic, which is a pretty cool little town, and of course home to the famous Mystic Pizza. (Which I did NOT eat at, by the way. The reviews were terrible.)
Then I drove along the coast through Stonington and over into Rhode Island, which I found to be pretty much identical to Connecticut. Haha. Here are some photos from Watch Hill Cove, which was a beautiful spot to stop and walk around.
