Where are some of the best fishing areas Vineyard Sound? Getting back in trolling.
I chatted with a Dockwa boater a while back who's involved with SaltyCape. They put out regular updates about what fish they're running into in what spots, complete with really well-done videos. That section linked is specifically for Vineyard Sound, but as the name SaltyCape would indicate they cover more waters than just that.
Wasque off of Edgartown is one of the best spots around, stop on by!
