I just don't get it. I'm certainly sorry he got hurt, but it isn't the ski area's fault he charged into something blind and assumed he knew what he is getting into. Ski areas have no obligation to sign hazards (at least not in CO and I see no indication that is different in UT), but in this case, there isn't even a clear hazard, just a change in how the slope was groomed. Come on now.
I commute by motorcycle about 25 miles each way. Right now that commute runs through a construction project where they have realigned the road several times. If I sleepwalked my bike through the construction zone and sailed off the road because I expected it to be where it used to be, I would get laughed out of court, regardless of how bad I got hurt.
