I wrote below that our winter residence is now in eastern Nevada, which probably evoked mental images of casinos, show girls, glitz, and libertarian values. Those are only somewhat accurate, once you head northeast out of Las Vegas on I-15.
I-15 comes out of the greater Los Angeles area, passes through Las Vegas, continues on through Salt Lake City, and continues north to the Canadian border. The Canadian connecting route heads farther north to Calgary and Edmonton.
Between Salt Lake and Calgary there are no big cities for 885 miles. Interstate speed limits of 75 and 80 mph are common, and often enough exceeded (but not by me).
North of Las Vegas I-15 passes through eastern Nevada and a corner of Arizona before entering Utah a few miles south of St. George. Basically everything north of Vegas is culturally "Baja Utah," with the thinnest of Nevada veneers.
This is because this area was essentially founded by homesteading settlers sent from Utah. For that matter, eastern Idaho and western Wyoming along the I-15 corridor are basically "Alta Utah," settled the same way.
