Glad I learnt there is something called Tent Pegging from this thread. As they say, what you know is just a drop....
It's fabulous! Play those videos someone attached. Rather different from our stuff; in the videos, they are riding country-breds (look at their ears, they curl in) and being Chaudhrys, Punjabi gentry, they probably have a string of four or five mounts or even more. We were rather more regimented, and I was taught by the same riding-master who had taught my father thirty years earlier, very strict, and no exuberance, no battle-cries, no twirling the lance, nothing, just the peg and a total focus. Our mounts were far, far superior.
Incidentally, when I was very young, A. C. Muthiah used to come to Calcutta for the polo, Polo at Xmas, we called it, the only chap from the south we saw playing. His uncle, of course, was a noted racing eminence, but he was more into polo.
Don't get me started on horses, I was crazy about riding, and used to feel uncomfortable and out of sorts on Mondays, that was always bran mash day.
