Usually listen to music, laugh if someone takes a spill. I've tried strapping in my binding..never get close.
I do this all the time, the trick is you have to be the only person on that chair and you turn sideways so your legs are on the chair seat, you prop the tail end of the board up on the back of the seat, then it's a piece of cake. Hope that helps.
