In an otherwise flat and forlorn section of desert between Tucson and San Diego, exit 67 on I-8 is a sweet pit stop: Dateland! A grove of date palms was planted beside the railroad tracks here in the 1920s. Today, it's more than just a typical refueling station—it's a true road-trip oasis for your sweet tooth. Sample the variety of caramel ovals, and then get a milkshake! The date shakes are definitely "local-" if not "world"-famous, and prickly pear cactus fruit is also a flavor option. Look for the palms on the horizon about an hour east of Yuma; it's not a mirage.
