That's a pretty low population in that area as far as people and mountain bikers are probably few and far between. Your best bet would be to head west and ride Jakes at Kinzua/Allegany National Forest (near Warren, PA). Northwest to Ellicottville, NY/Macarthy Hill SF. Those two trail systems are fantastic and big, so it makes the drive worth it. Ellicottville has an IMBA epic deisgnation. +30 miles of handbuilt single track. Jake's Rocks is machine built, but amazing. you can see youtube videos of most of the trails there.
