Honestly, this is one that you can walk around in, and not really bother with a tour. As excited as they are about their "reverse falls" and the Bay of Fundy, I found the paper mill across from the lookout point to be a real blight on this natural phenomenon. Just not an exciting town. Very nice people though.
Boston is a real city. Need more time to check out a variety of places and things. So much history, so much good seafood, needs a full day from 7a.m. to 7 pm, or something like that.
