Waiting For the Light

This is a context shot to illustrate part of the story below. Several bus loads of people came by, and in between, it was so hushed and momentous-seeming.
When they'd arrive, in a burst of noise and exhaust, they would disembark, mosey on over and commence to chat. It was like a commercial break from the Main Show. They'd pet the dog and tell me I missed a spot, talk about where they were from and then jump on the bus and ride away.
This shot was taken right before I put in the shadow of Mexico on the American canyon wall. I had to wait till it was juuuuuuust right.
