OK....this photo is actually a couple weeks old...its from when we drove from New Mexico to Arizona on our recent camping trip. We drove through a small sandstorm on the I-40. We missed most of it and drove through the tail-end. To put in perspective, the highway is very straight and flat...you should be able to see WAY into the distance.
Michelle took this with her iPhone and emailed it to me. Don't see that too often in Ocean Beach :)
