Great lists, everyone! Great job!
I noticed most mentioned about Mystic Seaport and Mystic Aquarium but you guys forgot to mention Mystic Village which has great shops to browse through.
Also, there are two great places to go is Oyster Festival in two cities on different dates. They're in Norwalk and Milford, CT. One for Norwalk is usually every Fall. The link:
Norwalk Seaport Association Oyster Festival
One for Milford is usually every late Summer. The link:
