Not Mystic, but it is in southern New England. The beige roof to the right is clearly visible on GE and is a social hub for the sailing set. What is atypical is the relatively open anchorage for the month of August. It it helps, the view is looking to the South.
Don't want to make this too easy, but the following view shows docks associated with the aforementioned building. Those who have been here will recognize this instantly. Another clue: GE shows a winter view, with the harbor and floating docks removed.
