Chile Pepper, if you like to kayak, there are a ton of sea kayaking opportunities around the midcoast Maine area (Rockland/Belfast/Camden). I like the Sebago Lake area, too (especially for camping), but I adore Camden. If you need a B&B rec there, I like the Camden Maine Stay. If you decide to venture further north to Bar Harbor, make sure that you get up to see the sunrise on Cadillac Mountain (and take a blanket-- its cold up there!) and have popovers later at Jordan Pond.

Don't forget to hit the LLBean (flagship and outlet) in Freeport! Sometimes you can pick up some great discounted gear at the outlet, and the flagship is open 24 hours. They also have 20-30 mi group road rides from the main store on Saturday mornings.
