Wonderful! We used to vacation in Rockland and Camden often on the 90's and the early 2000's. I highly recommend a short and pleasant drive north from Bath to Rockland to visit the Owls Head transportation Museum. On display are Cars, and Aircraft and stationary engines. The finest I have ever visited.
They used to perform live airshows. First time I went there in the early 90's there was a guy doing stunts in a Fokker Triplane. These are non existent so I really don't know what I was looking at! I have to find photos, from 30 years ago! I may also suggest the Fansworth art Museum. Enjoy! = Ken
