After watching what they were doing in that half pipe out in Salt Lake last night I can see how you could wreck yourself pretty quick. Having ruptured a couple of discs in the same area I will give you this advice. When you start to feel better, take it easy. I learned the hard way it's best to let things heal completely before resuming normal activities. Better to miss a couple of months of the season than a year.
Here's to a full recovery.
