I have never rode there but many of the wellsville guys in that vid come down to Pa to play on the coal hills. From my understanding, wellsville is not too terrible steep. The things that make their hills challenging are the roots, rocks, ruts, ect. All those guys basically run are stock 450s, 400s, and 250r(370's). And as you can see they mostly run knobbies or pro wedge tires. When they come to pa, most of them all put on longer swingers and all run paddles for our steeps. I will say one thing about those boys, there are fearless and care not one bit about fucking up there quad/bike. They have way bigger balls then ability. Haha. They are cool as fuck tho.
