I spent many a summer up here as a kid. My family had a "camp" on a lake north of here. I moved to Maine more than twenty years ago, I will never leave! Folks up hear are the some of the friendliest you will ever meet. There are things to do year round. As you already know, the winters can be tough by Southern standards, but they are not that bad. You cannot beat summer and fall.
Except for the Portland area restaurants are not the best, but that is changing quickly. But local seafood....that is another story!!! What more can I say????? I love this place.... does it show!!!!
If you have any questions, feel free to PM me.
P.S. I forgot to say there is some great camping!
