UMC does a WinterX where they use the actual track and just let you go at it while covered in snow, no prep or anything to the track. There is one tomorrow! One of these days I will buy a helmet and be abel to go to stuff like this. No idea of price, since you need to either have or create an account to get that info. Link Below!
