Ride up the Peak and Glacier chairs and keep your eyes open. There are lots of cliffs. Also, buy the "Advanced Guide to Whistler Blackcomb" (its called something like that, its available everywhere in the village). Anything more is too hard to explain and/or we don't want you poaching our secret spots.
i got dominator snaked on me last year. ask dave, we were scopin, then BAM like 8 dudes on it. then again, on a mountain where youve gotta be the early bird to hit something like jordan... well thats a horse of a different flavor entirely.
