As we left Tucson for Amarillo this Christmas, we couldn't believe how much traffic was heading East on I-10. I know it was the Saturday before Christmas, but it was stop and go for a while, and when we stopped at the rest area in the Dragoons, it was packed with cars, almost all of them carrying tarped loads like the ones in the photos. All the spaces were full, so people were pulled along the side with their loads. The line for the bathroom was a half hour long. The tarped loads and trucks with their rear ends almot couhing the ground made it look like a modern day Grapes of Wrath style migration.
