Country Doc's house calls are a hike down Grand Canyon

Family practitioner Ken Jackson is known around Kingman, AZ as the "Cowboy Baby Doctor," though he says the nickname is a bit misleading — he doesn't always ride a horse or wear his cowboy hat, and he prefers alternative rock to country music. But for the past 16 years, Jackson has traveled by horseback once a month deep into the Grand Canyon to provide prenatal care for Supai, a remote Native American village of about 400 that is inaccessible by automobile. It is the last place in the USA to which the U.S. Postal Service makes deliveries by mule.
