Alright, here's the lowdown on Western State and the surrounding area.
Western state is one of the smaller colleges in Colorado. Enrollment is around 2,500 and while in recent years there have been more and more women around...there still isn't a lot of women. There is a reason why the "Gunnison-ratio" exists. About 3 to 1 typically. Education at the college actually isn't bad for the money you would be paying. Western is NOT CU, UofU, or any other university. It's a small state college. There are some easy classes at Western, there are some very difficult classes (Macroeconomics with Dr. Plante for example).
Lots of parties because that's about all there really is to do in this valley. Not at all hard to find parties. The party scene however gets old because of the same people at every party. Oh, and since Gunnison is a small town....drama drama drama and everyone knows about your drama. Very chill people here though, usually very nice. Crested Butte is much the same...only smaller.
Skiing. I work for CBMR (Crested Butte Mountain Resort) currently. This year may in fact be a record setting year. CB's all time high for snowfall in a season is 415"...we're at 399" so far. It's been very good this year. You don't ski CB for the same reasons you ski Breck, Keystone, or Copper. CB's park sucks! Their terrain on the otherhand is ridiculous. Everything from steep glades, to pillow lines, to scare yourself steeps...all inbounds and not much hiking. One thing to keep in mind though, it currently costs $550 for a college pass and there aren't many perks to that pass. You get 3 free days at nearby Monarch, Telluride, Taos and Angelfire. It's kinda a rip off. Like it was said before, everyone is a dang good skier at CB. Powder gets tracked really fast, and typically doesn't stay "fresh" for many days after a storm unless it's been really cold. I have seen everyone from 6-year olds to 70-year olds ski Phoenix and Spellbound bowls.
Other outdoor recreation. Amazing! Everything. Kayaking, mountain biking, single track, backpacking (3 wilderness areas near Gunnison), fishing, climb 14,000ft peaks, boating (Colorad's largest body of water...9 miles away), cliff jumping (60ft+). Tons of things to do. Longboarding on campus is super fun. Get an idea of what to do and where to do it....and go basically. WP (Wilderness Pursuits) through the college is extremely helpful. They have tons of gear.
Hope that makes it easier
