We've been heading down cape since the 1960s. Chatham has always been our destination. My wife worked at a place called the Christopher Ryder House, which is now gone. It was a Dirty Dancing resort--full of food, drinks and then entertainment. I first went four years after her, as I started my Military career as an Infantry Officer. (not there obviously).
Anyway, this short video does Chatham a good service and is a wonderful overview of the 6000 person village.
