Example:
6 guys, LeMans start. Engines dead. Shifter race will have pushers 5 feet behind kart. Green flag drops, pushers push their karts off.
After the 1st lap is completed, the kart running last after every lap is black flagged until the last man stands.
Terry Riggins runs these in Great Lakes SKUSA. They seem to be alot of fun.
For TaG you utilize the same concept, but make the drivers run from across the track, jump in and T a G!
