Flying o'er the sands

…While the sands o’ life shall run.

-Robert Burns

We knew all about singing sands, shifting sands, drifting sands, white sands and painted deserts…but we hadn’t seen running sands until they ran straight at us, we riding north and they blowing south. They stayed near the ground and erased our camels’ legs below the knee so that, looking down, we felt we were flying over clouds.
