For a quick fix of rock crawling (really quick) you can check out the rock pile at the Clay Pits.
Snow should be falling, Head up to Butte Meadows off of hwy 32 or head up the Skyway... Through Paradise, past Magalia, past Sterling City and past Inskip.
Post up and get someone to go with you. Starting next weekend, there should be lots of folks up there looking for their Christmas tree.
