I finally learned in a place called Crip's Hole near the Gemini Bridges Trail outside of Moab.
#1. It was in the middle of nowhere so there was nobody around to see me screw up.
#2. The sand traps were endless, so you stalled again and again and had to clip out at the last minute.
#3. It was like riding through a sandbox. When I screwed up, I fell over and it didn't hurt.
#4. After laughing my ***** off a few times lying there in the sand, I really got the hang of it.
#5. As a bonus, my skills riding through sand traps improved 100% in a single afternoon.
