Having arrived in Boston after one connection in Minneapolis, we grabbed our rental car and took off.
We stopped at the Lexington green where the first shot of the American Revolution was fired, and then went to the Minute Man Park visitor center. They have the best presentation there. It uses multiple media and gives a great overview of those first couple of days. Don't miss it if you go.
I took the kids to an original 18th century colonial inn in Concord to eat, and we then drove up to Rockport, Maine after all of this. Arrived just before 10 p.m.
