Bronco Jump … Rick (doubling Bill Murray) landed an antique Bronco from a large jump into boxes and then onto the ground from a smaller jump. Its extremely short wheelbase makes this a difficult vehicle to jump; Rick had the extra challenge of being directed not to damage the Bronco. Meticulous planning, several radar gun measured practice runs through the take-off ramp area, and extensive experience combined to create an exciting stunt that resulted in zero damage to the antique vehicle.
