I live in Las Vegas and been there twice.Both times I scared my self so bad I had to wipe my shorts.The first time I was on my LT500R hallin ass up the tall part of the dune at night and went over the razorback(didnt see it till it was to late). Then I stalled it in the air ,oh sh*t no lights! The second time I was on my LTR450 during the day.I was hallin ass again across the face of a step ass hill.Just got back from Sand Mountain in Utah after 2 days of riding. The dunes there you have plenty of shut down area when you come down.The thing is after 2 days riding in big dunes the next day in little dunes I forgot where I was at . Back to hallin ass across the face ,when I came back down that step hill I roosted like there was a nice 200 yard smooth shut down,not. I hit a razor back right on the bottom of the hill and flew 20 or so feet then start pointing down. When I hit my body was laying on the front part of the quad, eyeballs 6 inches away from ground and legs locked in between handlebars and quad.I got lucky,my fried comes up after it happens and was freakin out ,I was ok.He siad look over there and about 10 feet away by where I launched then landed there was a spot with white painted rocks in a circle and flowers.I think we know what that means.I shit you not.After that one I learned to respect the Dunes, my quad or where ever I ride.I think somebody was watching out for me that day,I believe.Ya I been there and thats my experience at Armagosa dunes.That place will trick you ,ride safe.
