Bill, believe it or not, when I was a little kid, my dad used to take us to that island in his 1960 Grady White 18' Runabout with a 75HP Evinrude on it! What a beautiful boat! I had the classic lapstrake wood hull and mahogany decks. It was ALWAYS garage kept until a couple years ago, when he donated it to the Mariners Museum in Newport News, VA.
That island was never that busy back in the early 70's!
