Big White, huh? Tons of teaching talent there.
Are you a serious skier looking for your limits? See if you can get Steve Smart, although he might be a tough ticket to get. I believe he does all their technical training there, so you can be fairly sure any of their instructors will be well trained.
Do you want to be inspired by a young talent? Jesse Blackstaffe, only in his early 20's, but well on his way to the big leagues.
Ultimate zen experience: see if Crazy Mike is around.
You should check out Silver Star in nearby Vernon as well. Again, top-notch technical training goes on there, so you can be sure any instructor in the line up is well and thoroughly trained.
Have fun, sounds like they're getting the snow now!
