my first season out here. I've been running the same 3 single track trails in snowmass where I live, as most of that area is still closed from mud till june 20ish. I'll be looking for jumps once I get used to my new bike. Most people I've talked to in shops have told me carbondale is where all the mtb riders are this time of year, so I bet there would be some jump sets around there.
Once snowmass thaws out I'll be riding the lifts there pretty often. I still haven't found anyone to ride with yet. Let me know if you want to rock down some single track and I can take you through what I've found so far or if you find any jumps/pump tracks/fun trails.
