Not me, I love sun and slush bumps. Can't wait for saturday.
That said, I've been doing the March demo day at Xtal for 4 or 5 years now, and haven't had great snow yet. That is despite several *very* good Marches the last few years. There was one year with very nice knee deep snow on limited north facing aspects that never get touched by sun (everything else was seriously sun affected). But that's it that I can recall. In general, it doesn't seem to ever be a good day to demo powder skis. Just bad luck.
Any way to find out what they will have on hand to try out? I'm skiing Friday and family comes in from out of town for the weekend but...if there were a few skis I knew I wanted to try at the demo I'd uh...figure out a way to ski Saturday too and still keep the peace.
