I live in Forest Co. They're putting 38 miles of trails in at Duhring near Marienville. I met John Crandell over there this fall checking/working on the trails. He's an endurance rider that's won the Tevis and Old Dominion rides. The ones I rode I didn't think were difficult.
SpiritLifter, The Cook Forest trails that you ride ... are they at the park or at Ray's Scenic Trail rides? I know they put more trails in at the park, but not sure where the parking is. The old ones they had I rode once, but they weren't very long.
If anyone comes this way give me a shout, I'll try to meet up with you as long as you're safe to ride with. I have a messed up back and only travel at a walk.
I belong to the NHLA National Horse Lovers Association - Home Check them out...don't let "national" fool you. Most of the members are from Portersville, New Castle, Butler area and most of the rides are NW PA. They ride as Moraine, Raccoon, Flying W Ranch, Duhring, 2 Mile Run (that is a nice place with decent trails in Venango Co), etc.. check out the schedule.
I want to try finding someplaces to ride in E PA. I've talked to some gals that ride near Forksville and Renova...hope to get there next yr.
