When I lived in California (and at one point in the Mojave Desert), the sand did a number on my poor car engine. Sand made a mess of everything whenever I'd venture through the desert.
So I can't imagine what a nightmare this was for cars, eyes, computer equipment, etc. It's video from the massive sandstorm that hit Phoenix a few days ago.
The third video with a POV shot of driving into the sandstorm is insane!
