One time I was headed back home to San Antonio to visit my family, and right as I crossed over the Texas-Oklahoma border — somewhere near Denison, TX — a dust storm took hold. In a matter of moments the sky was red, the highways were covered, and dust devils swirled every which way around the car as we poked our way down the highway at geriatric speeds.
It looked very similar to the picture above, taken during a Lubbock, Texas dust storm in December of 2003. Check out this photo gallery to see just how thick it can get. [via]
