Me and Doohan were barrel racing one day, and as we went around the third barrel.. (I know, I probably shouldn't have been doing barrels on a 17.3 ex-racer TB who is clumsy as all hell and very leggy, but you know) and as we went around the third barrel he lost his footing, and his offside of his hind quarters hit the ground with a thud, but he didn't hurt himself, and got up, but instead of just shaking himself off when he got up, he thought it was necessary to start rearing, and on the fifth rear he was on a vertical and the wrong angle and was very close to going over backwards, I was scared I was going to hurt him when I did this, but it was that or we both get hurt and he most likely would have been awfully injured.. but I ripped one side of his reins and hoped to dear god his head would fall after them, and thank god it did.. he landed safely, and I landed in a very unconfortable spot right on his neck, but I managed to climb back aboard and trot the rest of the course :)
