Wow - I guess I'm in the minority here to say I LOVE the Spring craziness! I love the apres concerts, I love everyone feeling their oats a bit...I'm right there in the mix!
I don't really notice too many more collisions, or rudeness on the slopes - although we never really get SO crowed here. No lines ever. We certainly have bigger crowds during the Spring Break weeks...but the slopes are still pretty normal. In downtown Aspen (off the hill), the big problem is Gapers.
Gaper: usually clad in fur coat & boots, a cowboy hat, standing in the middle of the street, perhaps snapping a photo while blocking traffic, walking with strollers in the road, etc, etc. They also tend to snap fingers at bartenders in hopes to expedite their drink orders. On the hill, watch for flowing bleached hair out of a poofy headband, Chanel sunglasses and a fabulous Bogner one-piece.
The streets of Aspen are a dangerous place, I tell ya!!
