I would easily pick Canada over the US resorts. Bigger snowfalls overall, bigger terrain, cold temps. Whistler/Blacomb would be on the list, but I think I would gravitate towards Kicking Horse or Revelstoke. Both are a bit more off the map and have fantastic looking terrain plus good snowfall.
Hell yeah! If you want the potential to be eaten alive in bounds then Kicking Horse is where it's at. Its a slightly weird resort, 3 ridges with the beginner run running through the valleys in between. Not beginner friendly at all, some serious steeps going on. I remember being their on an epic pow day, jacked up on fresh snow and Tim Hortons. Front flipped off of a cornice and totally underestimated how steep these faces were. Several hundred vertical feet later I'm in the valley after a loooooooong trip!
I'm also Revelstoked! Nuts resort, if they can carry out the expansions they have planned it's going to be insane.
You gotta love it when your job means you have Lake Louise, Sunshine, Marmot Basin, Revelstoke, Kicking Horse, Panorama, Fernie and of course the epic friday night riding at the Mt Norquay park all within day trip distance.
As for me though, I still want to hit up Big White and Whistler of course. So many european resorts that I need to check out, I just love europe, being able to hit up the bakery on the way to the lift is one of my favourite things about france. Also theres so many epic resorts in the US that I need to ride, its hard to just pick a couple!
