Just off the highway there are a plethora of adventures awaiting the exploratory traveler. Host David Yetman heads west of Tucson to visit some of these undiscovered places. After visiting the largest dune field in the United States, we head to Yuma for a hot air balloon ride and a walk through "the hell-hole of Arizona," the Arizona Territorial Prison. Other stops include the Sonoran Desert National Monument and Picacho Peak State Park.
