You nailed it! Sergeant York had just reared up and did a 360 in the road. I was lucky to get a shot of him actually going in the right direction.
Any idea what he reared at? Although that's hard to say, some horses get spooked at absolutely nothing. Somewhere I have a Tshirt with three cartoon horses on the front with big round eyes. First horse: "What's that?" Second horse: "I dunno." Third horse: "LET'S SPOOK!"
Hope no little kids threw pebbles under his feet.
