Explanation of Contest:

Modified Tough Trucks is a side-by-side, bracketed contest on an obstacle course. The course design will vary at each Jamboree depending on the local terrain. The course is designed to challenge the driver’s skills. Contestants should check the event schedule for Tough Trucks times. Transponders will be used for timing.
