Another suggestion: I don't know where you are coming from, but if you are interested in the Ocean...
Camp at Fisherman's Memorial State Park in Rhode Island:
Fisherman's Memorial
Take the Tw's to Block Island on the ferry:
Block Island Ferry
You can see the whole island in a day on the bikes...most of the roads are gravel, so the TW is the perfect way to get around.
Block Island
Have lunch on the porch of the Island House Hotel. Visit Southeast Light
southeast lighthouse
Once you get back to Galilee, have a seafood feast at Champlin's
Champlin"s...1-1/4lb Lobster Dinner,...Mmm, Mmmm
Oh, and personaly, I'd take September over August...much less crowded.
