New Hampshire Riding – Looking for Info

My riding buddies and I are thinking about heading up to New Hampshire for a fall ride, maybe in October. Some of the places we heard about are:

Little Monadnock
Little Monadnock Family Trails – New Hampshire Motorcycle and ATV Trails

Ride the Wilds
NH Grand : Ride The Wilds

Please let me know if you are familiar with these riding areas, what you think, suggestions for other places, best times to go, and any other conventional wisdom you can share.

Thanks!
