Having set up camp alongside the Colorado River near Parker, Arizona, my adventurous wife, Barbara, decided to take our trusty “toad” compact car to see a real ghost town. It was a pleasant and warm day, barely a cloud in the sky. But we did not take our 2019 Ford Fiesta to the Tombstone “ghost town,” where the Shootout at the O.K. Corral made Wyatt Earp famous in 1881, and where tourists today can see a tamer, bloodless reenactment of the same while sipping on a cold craft brew. No, not Tombstone.
