Maine is known for its ponds. And don't let the word "pond" fool you into thinking that's a small place. A pond can be as big as any lake you might imagine. And believe me when I tell you, there're fish in those ponds. Big ones.
So rent a canoe, find a friend, put your rods in, and pull your waders up, get your bucket of worms, and get yourself into one of those gorgeous ponds. Half a day, a whole day -- whatever works for you. Because name a pond, any pond, and that's all you need.
P.S. I don't fish. I just float. And that makes me plenty happy.
