I went skiing there for the first time two weeks ago and I was impressed. I can't think of a better place to go near Spokane. Red Mountain is steep, uncrowded and friendly. It reminds me of the local ski areas we have in Montana but with better tree skiing. Rossland is an old mining town that is much like all the old mining towns in Colorado before they were overran. I really enjoyed the town and people there.
PS - Be sure to take a passport or birth certificate so they'll let you back in the USA. Also, they have some great Canadian brews up there.....I'm now throroughly disgusted with the garbage they send us.
