Man, I just got back from there also. Wish I saw that vid before I went, so I could have tried it myself--didn't know where exactly Corbets was located and thought it was probably a bit more extreme than that. Pretty intimidating up there with 10-15' visibility not knowing where you're going.
First time there myself...one of my favorite places so far. Hardly spent any time on groomers the whole 5 days, except when traversing. Got some really nice runs hiking over to headwall and from the spider crawl above bridger over to crags area. Hobacks area was pretty sweet, as well as the area next to it straight down from laramie bowl. The backcountry stuff that was easily accessible--like rock springs and cody--seemed to actually get tracked out much faster than the inbounds hikable terrain.
Need to get myself in better shape before next time, lots of hiking required to get the most out of your experience out there. Wore myself down pretty bad and managed to catch a nasty chest cold on my way out.
