How important is the park to you? Can you work a compromise and agree not do the jumps (or only small jumps)? Your parents are being overly reactive but there are some pretty big risks in the sport.
Park is really fun to me, but I'm definitely no expert at it yet. I guess I push myself pretty hard to get better and that's why I got injured. My parents are scared of the mountain in general - they think I'm gonna die out there or something.
Thanks for all the advice though! I'll try and compromise and say that I'll stay out of park for the rest of this season (maybe haha)
