Right Turn at Sunrise Ski Area. Fast, fun downhill.
Top sections tends to be a bit rocky, while bottom sections are mostly hard-packed.
I'm sure they're done with that, but it should be intersting to see how that impacts next summers trails. Your arms, yor legs, your chest, your head will ache when it's all said and done, but you'll think you're a damn cool dude as you drive off into the sunset. There are, apparently, some cross-country trails at the ski resort, but have never found them. There is a lodge with showers and food and toilets, but if you're looking for a vacation, lube up the beach cruiser and head somewhere flat.
