I once dropped in on a 10ft quarter pipe, just to have a little kid magically appear at the bottom. I couldn’t slow down enough, and slammed into him pretty hard. He was ok, just shaken up. His giant, muscle bound, jock Dad got all up in my face, and called me a loser for being a grown man at a “kids” skatepark. He was 2 sec away from knocking me out, and he could have with ease. So yeah, that bugged me.
