I don't know about the coal powered generators, but doesn't it make sense that those people had SUVs if they spread across the Americas so fast? Something pre- IH Scout or Range Rover at least?

Lewis met with Jefferson on the east tidewater one summer, spent the next winter in Pittsburgh building boats, spent the third on the banks of the Missouri in North Dakota with the Indians, and the very next winter he was on the Pacific Coast watching the sun go down. Came back in even less time.
