This is a sand storm. It sand blasts your paint right off your car! You just wench and wiggle in your seat when you hear it hit the car. The wind was blowing between 50 and 75 miles and hour. How much fun was that?? Can't see and blowing all over the road! Good thing we were in a heavy truck,and knew the freeway and all the short cuts when it stopped moving.There only are a few and we were lucky enough to be at the spots. There is only one freeway to Vegas from So. Ca.
