ralann,
There's a SG this weekend at Northstar at Tahoe. Its run by Sierra League. I think anyone can enter. I did it two years ago and had a blast. Its run with ski gates, but you can armor up in case you hit any. They run it down Challenger which has a long flat in the middle that tests your tucking ability. I think I ran it in about 1:20, but I could be wrong. I can't do it this year. :(
Its a long drive, but its driveable.
