There is a great lobster restaurant right on the water a short drive from
Belfast, Me (BST).

But if you're up there late next week, the place to go is the International
Seaplane Fly-In on Moosehead Lake at Greenville, Me.
Great atmosphere and some incredible flying during the short takeoff
contests and bush pilot races.
Maybe the DC3 on floats will be flying.
A litttle different than the Oshkosh experience.

There's a shuttle bus from Greenville (3B1)
