I will be making my first visit to Maine / New Hampshire in a couple of weeks and welcome suggestions on things to see and do. I definitely want to see the Portsmouth, Kennebunkport areas, but would also like to also venture into New Hampshire. Primarily, I am interested in good hiking locations in either state. Additionally, I would like to see a few covered bridges and the like that are indicative of the region. I am prepared to do some extensive driving and would appreciate any suggestions of "must see", "must do" activities.
