Replying to Theta xi? (cu boulder)

so this is the self proclaimed "outdoor sports" fraternity at cu boulder, i checked out their rush video, has alot of things i like to do (freestyle skiing etc) and i was wondering if anyone on NS knows anything about it.  It looks really cool but i'm afraid its gonna end up being a bunch of overly pumped up "bros" with too much testosterone..

anyone who goes to cu/knows anything about this frat, answers would be very much appreciated.

here is the rush video
