Those cat tracks teach you good edge control. I've been riding forty days a year for about five years now, just got back from whistler this past weekend and I still find several of the cat tracks there a pain in the ass.
Remember to keep a good stance, knees bent. Keep you weight evenly distributed front to back, don't wind up with heavy pressure on your back foot. Don't be afraid to rest, but pick your moments, rest at the crests, stopping in the low spots means skating uphill. The blackcomb side has less cat tracks than the whistler side, especially with the new crystal express.
And even who it's at it's most annoying remember you're very lucky to live nearby, here in ontario there's no cat tracks and no good hills.
