All these spots will be mobbed on July 4 weekend, Hadley perhaps the worst of all. Off Menemsha (this being the open water of the Sound) has lots of room, but no one wants to be there excepting an excellent weather forecast.
The Vineyard lagoon is the only place I know for MV with the anchorage area (large) to happily handle the demand (low).
