John,
Growing up on the MS gulf coast there was too much rain for a dust storm and it took a hurricane to get the beach sand off of the ground. Three years in Lubbock TX was bad enough, I wouldn't have lasted a week in the Sudan area.
After moving to IL I traded in the Monte Carlo SS I had out there and the salesguy noted that the privacy glass in his shower was clearer than my windshield. The paint held its gloss (waxed and covered) but the windshield suffered. Probably the fastest 5 miles I ever ran was on the return trip to the university after seeing a wall of dust heading for me. I made it with maybe 2 minutes to spare. Dust storms are one of the MANY things I don't miss about Lubbock.
