Annual Sunshine: 263 days
Texas' northernmost sunny town, Amarillo can be found between Oklahoma City and Albuquerque, New Mexico (coming up!), and 72 percent of its days are glowing with sunshine.
Here, too, are tons of museums, a zoo, botanical gardens and the Palo Duro Canyon State Park, which is a 60-mile ravine between 800-foot cliffs that make for some dramatic scenery and hikes.
Oh, yes, it's also home to Cadillac Ranch, where buried painted cars burst from the ground — a road tripper's must-stop.
