Shelf Road is tough anytime. Wish I was on it right now-NOT
Wouldn't be fun today, though. Eeesh ... just had a nasty flashback to the day I got stuck on Rampart Range Road on a bright, sunny December day ... but the wind started blowing hard, and the road got blocked by a couple feet of snow in 30 minutes. We were lucky to get out of there.
That was the day I learned the true meaning of "Mountain Conditions Can Change Rapidly." I'm a lot more careful these days.
