Jud,
The good ones have been mentioned, but the Mass privates are not exactly easy to get on.
The status of Waverly Oaks is up in the air, but my guess is that it will re-open with the collapse of the movie-studio funding.
Newport National is also good in RI, as well as Triggs Memorial, the Ross muni in Providence.
The decent publics actually on the cape are Captains in Brewster, Old Barnstable, Dennis Pines/Highlands, and the ultimate Cape hidden gem, Highland Links in Truro.
