Sounds great. The train from Denver is so cool. I was in Vail, and rode mtn bike from base of Vail, up to the top, and back down. When I got to Vail village, they were just happening to be having Octoberfest - score!!! Regarding oxygen...I've always told people that the reason I acclimate so well to high altitudes is that I live in Jersey, and the amount of available oxygen there is about the same as the available oxygen at 10K feet.
