After I rode Zum in the round pen today, I was riding back to the corral and he spooked. I tried to use the one-rein stop but instead of stopping, Zum just ran around and around in a tight circle. I felt like he was going to fall over so I decided to jump off. I landed on my right hip. I am banged up and bruised. Zum ran away down the street. It is a miracle that he didn’t get hit by a car. Some girls caught him many blocks away. Why does he run away? Why doesn’t he stay by my other horses?
