You're wasting no time in getting acquainted with western mtb'ing - excellent. Next up, Crested Butte perhaps? Durango? Steamboat? Vail? Laramie? Aspen?
Yes, to all.
I've done Vail and surrounding trails many times (been coming to Vail every summer for the past seven years). In fact, I'll be doing Two Elk on 7/22 with FRMBP and then meeting up with my staff from my previous employer (conference at the Mariott).
