Re: Contest/Game - Identify this picture
I thought of Duxbury and checked it over too quickly--didn't zoom in enough. The cue for me was the rowing operation next door. There aren't too many places that would be suitable for rowing, accessible to open water, and have a yacht club next door. The shallow water was also a clue, particularly with the number of smaller power boats in evidence.
I was on my way back to recheck Duxbury when Rob nailed it. Oh, well. More power to Rob!
BTW, if you've checked the charts for this area, there aren't too many sailors taking a right turn as they come into the bay.
