OK, so Sporcle is officially the most amazing site ever. And for you knowledge hounds, I've dug up some horse games - and made one! - for your enjoyment. I totes encourage venturing into the rest of the site, though - the country-naming quiz is my addiction, and, sadly, my downfall.
Anywho, the quiz I made is for you eventing buffs - and it's pretty hard! No cheating ;) You can enter either the horse's name or the rider's name, in any order.
