Admittedly the simple answer is a few too many toys and interests and not enough time to do'em all! The WR allows me to ride public roadways around here too AND venture where the pavement ends (where permitted)
. I got the ATV's for seasonal versatility and because NH allows minors to ride (within their rules which are ok by me). Plus my son has no digits on his left hand and a motorcycle was/is a bigger challenge for him than a quad. I would go with the kids and we had a great time together. We've been to Hop/Everett. It's getting beat up though. So I stopped riding there. Me and the kids got lost in Sullivan County trails one time and we went thru hell and high water (literally) until it was dark and finally got back to civilization (we followed locals then broke off but took a wrong turn down a closed trail that was a stream full of holes and boulders). After that episode I always packed camping gear/flares in case of emergency. I usually go to Little Monadnock Family Trails in Swanzey near Keene
Now without the quad...
Been up to North Country in Stratford, Mt. Moosilake, Salmon Brook, Bear Brook State Park (for the annual Toys for Tots Ride), Jericho Mountain, Pisgah, Warren, etc. Like I said, I've covered a lot of ground in NH.
