I always where mine park or not. It makes me feel comfortable going outside of my normal range of things I try. Now when not hitting park you may think what can happen well this year my 3 friends and I went on a boarding trip. 3 of us hit park and the other guy would just cruise and bomb a couple hills. He was pretty experienced with handling speed, but one time he just caught an edge and had to go to the hospital. He had broken his collar bone and gotten a concussion. Ya the collar bone thing would of happened but if he had worn a helmet then when the ski patrol asked him where he lived he would probably actually be able to answer. But overall it's a choice.
