Just drove south from Phoenix to Tucson, Arizona.
There are many more saguaro cactus here.
Air pollution worse than usual:
dry as it is,
the air has a haze to it.

Phoenix is so terribly FLAT FLAT FLAT
regardless of the outcroppings of hills and mountains about it.
Tucson is another animal:
ridges, arroyos, ditches, steep rises.
It looks like permanent folds in a wrinkled crust of the earth.
Kind of fantastic to the eye.
