Maine travel information?

Hi! I am planning a trip along the coast from Portland to West Quoddy Head during the first two weeks of September. I'm looking for nude-friendly places to visit along the way: hiking; sunning on the shore (yes I know - rocky and chilly lol); cycling (yes I do ride naked sometimes); maybe social opportunities if they present themselves, and the like. Could anyone suggest nude friendly places that I might plan to visit? Thanks!
