Pictures taken from the car while driving through the high plains of Nevada, Utah, Wyoming, Colorado, New Mexico and Arizona. The land goes on forever and seems mostly arid, and the roads are mostly striaght. If you stay awake, there can be amazing colors and formations (sorry, hard to catch through the car window). Conduits of commerce on the asphalt, rails, and wires. An the history which amazes me: think of doing this in a covered wagon with a couple of oxen rather than an air-conditioned car.
