I was planning on doing it last weekend but it was 3 degrees(C) and snowing when we woke up so we passed on the pass. (btw -and fyi for those who are looking for some excellent rides in Canada - the highway is closed to vehicles 'till June 15 every year - couple a 100 k of nice paved road and you're only bound to meet other cyclists and the occasional elk. It's also the highest place you can ride to in the whole country-at least on pavement- at 2227 m)
