Sigh... Snowbird, I love you. But you kicked my butt.
Snowbird is truly intermediate to advanced territory. There were some runs here the likes of which I've never seen: chutes with moguls in the middle, trails with swooping turns and both shallow and steep parts in the same section, fun powder-bumps to get some air... (Ok look, I'm from the East Coast, we just don't have this sort of thing.) If you're going to push yourself to the next level, Snowbird is the place to do it. With all that soft, fluffy powder, you can bust big-time without having to get carted away in the little red sled thingy.
The only downside is that a lot of the trails are connected by narrow, flat snowcat trails. Those are no fun. It's hard to tell by the map which trails are real trails versus cat trails. Aw well, my legs needed a break anyway.
