Off-road Tomcars have opened up America’s final horizons, enabling us to discover both the lengths of our country’s untamed deserts and the mandatory jail sentences for playing chicken with border-patrol vehicles. Launch your own expedition with today’s Groupon: for $69, you get one admission to an off-road Tomcar tour from Green Zebra Adventures in Fort McDowell (a $129 value). The normal price for children younger than 12 and third and fourth riders is $59 each.

The Sonoran Desert’s rough-hewn topography tempts thrill-seeking Tomcar riders with steep inclines, craggy rock faces, and magnificent saguaro cacti on approximately 2.5 to three-hour tours tours that boast about two hours of drive time. A military-grade adventure vehicle capable of traversing nature’s most far-flung outposts, the sturdy Tomcar eschews asphalt to sate its dust-biting appetite on the pristine landscape of the Fort McDowell Mountain Preserve. Guides familiar with the local terrain offer their insights and jocund company on the wilderness jaunts, strapping into racing-style safety belts and leaving the serious driving up to licensed guests 18 years and older. Other passengers can brace themselves on the car’s steel roll cage as it rumbles through the Arizona wilderness, pausing only to switch drivers and graze on the desert shrubs that constitute much of its vehicular diet.

Guides inundate their fellow riders with a wealth of area knowledge throughout the tour, giving crash-course lectures on the Yavapai Nation and pointing out caves where feral Tomcars sometimes dwell. Though this Groupon does not include transportation from local hotels, all customers will receive an ice-cold bottle of water, goggles, and a bandana upon their arrival at the Green Zebra site. Tomcar drivers and passengers should come equipped with closed-toe shoes, comfortable clothes, towels, and plenty of sunscreen.
