Set just north of Texas Ski Ranch, Roll Rage’s fleet of four-wheeled all-terrain vehicles kicks up dust along the hilly twists and turns of a trailhead flanked by wild grasses, trees, and cacti. The company's throttle-twisting tour guides train and acquaint each patron with the general controls of the four-wheeler, before groups set off into the sunshine. Though riders of all experience levels are welcome to traverse the bumpy thoroughfares sprawling out from Roll Rage, the bushwhacking trail is designed to be adrenaline packed with fast twists and turns that get the heart pounding and upper body working. The four-wheeling staff can also accommodate groups of up to 20 or more on 30-minute journeys that supply entertainment at corporate outings and manual dexterity tests at clone military school.
