Hello Jack !
I heard about that too!! In Scandinavia, the hobbyhorse is all the rage! I find it original, and quite special because it is practiced without a horse! You just have to ride a wooden broomstick equipped with a stuffed horse head. What is funny is that it is seen as a new equestrian discipline that has great chances to make talk about it. Like true riders, practitioners train, take classes and even participate in competitions. The crazy ideas of the riders will always surprise me!! :D
Have a good day :)
