I got talked into showing one of my horses at the county fair once by a more than encouraging friend. I have a big, bay roan mare that I always just rode on the ranch. Her tail always got tangled in the brush when I rode her, and I used her so much, that I got sick and tired of tying a buckaroo knot in her tail. So I cut it off about ten inches below the bone. Then made a bunch of shoo flys. But anyways, I showed her in a halter class a just a county fair and got dead last. The judge said if she had a longer tail I would of won the class, but she didn't have the halter tail, nor a short chopped off mane. That's all I ever got of the show horse world lol. Tails do a lot for first impresssions in a horse show. They can even help cover up minor conformation flaws. If you want to be competitive, the look has a lot to do with it.
~Started young horses in Bosca te Ador, unto the two rein the old Spanish spade, brought them along with two hands that were gentle. Some fine reining horses as ever were made~
