Trails Around Corning, NY?

I had a nice place near Horseheads, an old gravel pit - no sure its still accessible - will have to check - been years but it was hours of riding fun - I never did explore the whole place in the few times I road there.

I have probably 800 acres here to ride for me & the kids, but the owners will not allow invites - lawsuits are the big concern with everyone.
