David,"Gymkhana" is a word I haven't seen used since Adam was a cowboy,,,
I alway associated the word with horse "trials" - a quick AV search shows it's tied up with car "racing". And, maybe general competetive sports...
I see the origin of the term as in India ca mid-1800s - sort of a Horsey game to play when you didn't have enough riders for a couple of Polo teams. Like, you'd ride flat tack on your horse, round a tight course. Object - pick up "souvenirs" from the ground - punt balls through hoops etc,,,
Is a motor gymkhana roughly the same?
