There is about five of us that get together on Sundays, and we go up through the Springfield, Grafton, Wilmot, area in New Hampshire. I called the Springfield town office and the lady there faxed me a map and list of all the class 6 roads. We found that once you actually get out on the trails you meet a bunch of people and they can usually tell you where you can go and where to stay away. Also there is a map, ( I got mine at Cumberland Farms) that is a geological map. It is a big red book and in there it shows you trails, old railroad beds and some class 6 roads also. I am not sure where in NH you live but if you are in the Andover- Franklin- New Loundon area, there is a lot trails, also if you see someone at the gas station, in a big 4X4, just ask, most everybody is super friendly and will be glad to let you know where the good mud holes are.
