Brutal dude. I know what it feels like to break an arm snowboarding. I did it coming off the backside of a 360 last season. I landed wrong, came down on my left arm and snap! I had to have pins and plates put in and now have two sick ass scars. It's still a little tender, and I sure do notice it every time I go to stop myself from falling. Here's to a quick recovery and sorry to hear about your season.
