When my daughters were young and we lived in Saudi Arabia, one of their greatest pleasures was to run down a sand hill like this at full tilt. Falling and getting as sandy as possible was a lot of the fun.
We loved the desert and regularly drove across it as well as across a treacherous tidal salt flat to get to a secluded beach on the Red Sea. We gradually learned which tracks to take so we wouldn't get stuck. If a path looked soft we would get out and test it by walking ahead of the truck.
Once we came across some local people whose pickup was stuck in sand. They were surprised to see three western females leap out of a jeep to help push them onto firmer ground.
