We just got back from a great week on the Vineyard.  I had lived on the island in the past but hadn't visited in a few years and had never visited with a child in tow so I used this web site extensively to find fun family activities.  When you are on the island pick up the "Vineyard Visitor" (the hardcopy version of the web site) free and available at most establishments that advertise with the paper.  More Martha's Vineyard tips to follow...Happy Trails!
