Sure there are some cool and beautiful little historic towns, but you’ll also see a lot of towns that are basically just two truck stops and an RV park. Sometimes also a hardware store or tourist trap. And then basically nothing but desert/cheatgrass or farmland for 20mi in every direction.
But if the alternative is 100s of miles of desert, having a gas station, convenience store, and run down motel every 20 miles doesn't seem so bad. Especially if you have a breakdown or just need to use the bathroom and get a snack.
