I have only ridden Boulder and Frisby Ridge, I really like Boulder, it's a great area, but it's also very popular and there can be a lot of sleds and the main spots can get pretty beat up in a hurry, You should still be able to find some good snow, it's a pretty big area, Frisby can also be fun, not as many open play areas, sometimes a little easier to find untouched snow, Bring a GPS if you don't know both areas, I have been suprised and got socked in by snow or fog in just a few minutes and it was hard to find the way out. Sicamous is only 45 minutes away too, it's also got some good spots. I think Revy is about to get blasted by snow, if your there on the 11 it might start getting cold, but it's still midweek with a huge dump of snow you should have a great time. Take lots of pics.
