I spent part of my career in the 1/17th CAV, 82nd, on Ft. Bragg.
The cav scouts introduced me to parachute surfing.
After a jump some of them would tie a chute to the back of a HMMWV. One would get in the driver seat and one would sit on top of the chute and hold on tight. The driver would haul ### around the DZ with the other guy in tow. Crazy stuff!
