How about I go first, and Start the ball rolling?
So, I used to ride this huge ex racehorse named Luck. Keep in mind that at this point hadn't been riding very long. So I was riding bareback for the first time in the indoor arena with some of my friends, when we decided to start trotting. Now Luck has tendon problems in his back two legs from his racing days, which causes him to pull up his leg really high and fast when he walks. Which makes his gaits really awkward, I did fine for a good while, but then I felt my self start to shift off to the right. So I thought ok its fine I'll just stop him and readjust my seat. So I stopped him and almost like in slow motion Luck shifted his weight and I started to slip off. I fell the full 16.3 hands onto my butt from a STANDSTILL in front of all of my friends.
