I went sandboarding before...Just like snowboarding except it takes more mustle to turn (because the sand is a lot heavier than snow). Wear googles and be prepared to get blasted with sand. As for sand skiing dont use your real skis, they wont go too fast. Sandboards have some synthetic plastic stuff on the bottom, I'll look it up and put up some directions.
