Well, anyone slick enough to catch a horse would surely notice it ws wearing a bracelet!!
When I was a kid, like 10ish, we were up at my great aunt's cabin way up north in MN. We woke up in the morning, and my dad told me there was a horse in the front yard. I went out in my pajamas and "caught" it, but they wouldn't let me keep him! They told me it was from the summer camp down the road, and I had to return it. I had a rope to lead him with, and as soon as I was out of sight of the house, I had that horse weaseled up against a bank at the side of the road, climbing on. The camp was happy to get him back...
