Aspen is buzzing with anticipation and getting ready to greet and cheer for the participants in the USA Pro Challenge, which arrives here tomorrow from Copper Mountain. Independence Pass will be closed tomorrow between 1-5:30pm to make way for the cycling teams as they complete Stage 3 of the week-long race. The finish line is on Main Street, so it too will be blocked off from 3rd Street to Hunter, beginning at 6am Wednesday morning. If you are arriving in Aspen tomorrow, you may want to plan to drive here via I-70 through Glenwood Springs and Highway 82.
