That's always what worries me about getting into tricks, I'm 35 and have rent/car payment's/etc. Then again I bomb down the mountain at the fastest speeds I can handle and let me tell you when some choppy terrain or a rock sticking up over the snow catches me off guard and I miss popping over it, I take some nasty tumbles. So after taking many of these nasty spills, at the end of this year I said "fuck it I only live once" and am picking up a more park friendly board for days I want to play there.
Keep it up man, don't let that rail tell you who's boss! I mean shit does happen, butt 99% of the time you will walk away just fine right? Right? LoL, eh fuck it.
