well you are sadly mistaken. Liberty does have decent jumps, they are just small. Roundtop built bigger shit this year, could have gone there. and don't even try to tell me big boulder doesn't have hittable jumps.
like williams said, you just have to make the effort.
and getting comfortable with jumps is just a process. if your not good at them, work at it. there are definately jumps in southern pa that will allow you to progress to a point. It is more about the kids you ride with than the type of parks/jumps you hit. there is a reason that roundtop has produced some amazing skiers. evan, pmin, bennyb, steve stepp (i could go on?) all would have killed to learn on the jumps lib had this year.
sorry it just pisses me off when people complain so much about those three resorts(whitetail, lib, roundtop). i spent a fair share of my time bashing it, but i am thankful for what that place provided me with, and i would look at skiing the way i do now because of it.
end rant.
