If I was going to the gathering I'd definitely go to Snow King. Likely the snow would be solid ice. Doesn't matter. Screw Jackson for a day. Maybe the week. Hit Targhee, maybe back country.
I should be more enamored of Jackson, not sure why I'm not. Dick's Ditch is pretty cool though. I could easily spend half a day in that. Maybe hit the Hobacks for some atrocious refreeze in the late afternoon.
Bill Briggs bought Snow King in 1966 and started the Great American Ski School there. I didn't know he'd started a Bill Brigg's Ski School in 1958 at Suicide Six in VT. Pretty cool. Clearly he likes steeps, even way back then. I learned to ski at Suicide. 800ft vert, two Pomas. The Face was steep and at the time I skied there still ungroomed. Too steep, you need a Winch Cat. People were always walking down because they fell on the Poma and couldn't ski down. If you could ski the Face decently you could go to most places and be ok. The Front Four at Stowe weren't much harder, but much longer.

"The history of the sport has been plagued by trumped-up 'right ways' to ski," observes veteran ski teacher Bill Briggs, 68, of Jackson Hole, Wyo. And, Briggs might add, plagued by criticism of "wrong" ways.
