to be honest, out of all the mountains on the east coast (that ive been to) Loon Mtn has the nicest/friendliest group of ns'ers. On any given day, there will be like 3-4 kids willing to help u out and learn new tricks. One kid last spring spent like 45 minutes helping me learn cork 7's when i asked him nicely to help me out.
.....and one time at killington, i was arguing wit my dad and an ns'er skied out over and tired to calm my dad down. lol.
main point - theres ns'ers everywhere. Go ski and have fun. Being helpful and friendly goes a long way.
