New England is beautiful at this time of the year. The leaves are just starting to turn and should be near or at peak next weekend. Definitely check with the state (link in previous post) to see just what the leaves are doing.
Have a wonderful trip! I'm very lucky, I get to see the glory of fall in New Hampshire every year! I just have to look out my windows at my 6 acres of trees.
