I was returning from high school one day and a runaway horse with a bridle on sped past a group of us into a farmer's yard looking for a drink of water. The horse was perspiring heavily. And the farmer didn't recognize it so we cornered it. I hopped on the horse's back. Since it had a bridle on, I took hold of the tick rein and said, "Giddy-up." Headed for the highway, I knew the horse would turn in the right direction. I didn't know what the right direction was. And the horse trotted and galloped along. Now and then he would forget he was on the highway and start into a field. So I would pull on him a bit and call his attention to the fact the highway was where he was supposed to be. And finally, about four miles from where I had boarded him, he turned into a farm yard and the farmer said, "So that's how that critter came back. Where did you find him?" I said, "About four miles from here." "How did you know you should come here?" I said, "I didn't know. The horse knew. All I did was keep his attention on the road.
