It's the end of July, in the middle of the desert. Everyday has been sun. Not the pleasant, carefree, have a picnic sun, but brutal I will kill you if you stand around out here much longer sun. Today it's weird. Overcast, dingy, of course still hot, but now oppressively humid. The light is a sickly warm grey, barely enough to light my office to paint, and the air is thick with... something. Moisture, dust, probably both, but occluding the mountains around us almost totally.
