It is really worth going and it is so close. You do get some fairly steep runs, and the lifts are really neat. One thing kind of nice there too is they have all these road side motels that have ski packages as well... most are family run with awesome food.
I would say for sure I like the West better, Whistler, & also Sunshine Area.
Just a little nicer and more variety in Canada's West.
However, yes Placid did have the Olympics... it is no slouch. A nice hill. Lots of other places close too, although I did not try them.
It is only 6 and half hours roughly to drive if I remember correctly, so it is close.
