Thank you for the welcome to the site
John, thank you for clarifying that the IFSW is indeed a film school and not an "obscure faction", should have made that a little clearer.
In relation to Buzkashi the sport goes all the way back to the time of Genghis Khan who although forbidding his people from having arms during peace time made hunting on horses compulsory as training for war. Riders would track their prey for weeks at a time eventually wearing down the animals before whipping or stoning them to death. Bloodletting was not practicing as to shed blood was believed to allow the soul to escape.
It's a wonderful, unique part of Afghan culture, a bit like going to the cinema here complete with popcorn sellers and other snack vendors.
Looking forward to getting it out there.
