I'm a boarder and see the odd numpty blocking the piste. Best to simply make your way to the side of the piste and not just over the ledge so boarders and skiers can't see you in good time.
Same for Skiers though, was bombing down the wall last year and banged the breaks on as a group of skiers stoped to chat and formed a nice line across the piste This happens quite a bit, the mind boggles.
I don't go in for this Trays vs Sticks malarky. Boarders or skiers - use common sense eh?
