We camped in MA, ME, Vt, and NY in early Sept through late Sept. Hit the color change in VT in mid-Sept and had a great time. In ME we stayed at a campground called Wild Duck Campground in Scarborough this was close to Portland ME and other towns we were interested in. The Campground was adults only campground no children allowed and very reasonable for full hook-ups with 50 AMP site. Portland Lobster Co is a good place to eat in Portland ME.
Another campground we stayed at was in VT called Limehurst Lake in Williamstown VT. This was near several attractions that we visited. Such as Green Mountain coffee, Ben and Jerry's Ice cream and the Rock of Ages quarry.
But like others say most campgrounds in the Midwest and Northeast close after Columbus day. Another area of concern for me was the road conditions in VT, the main interstates are great but some state highways 2 lane roads when crossing the mountains turn into dirt roads. I did not feel comfortable pulling my trailer up and over them. So we had to travel about 100 miles out of our way to cross them when traveling home. State highway 2 is a fully black top road but it does go through some towns and one portion does has a 8% grade if memory serves me right.
