The horse is trained the route through the park. Originally he only rode through frontierland, down to the Liberty Tree and back to the starting point. Some years back the expanded his route all the way down Main Street. But the horse is the one that does it all. And too many stupid people try to stand in the middle of the street. The rider has no sight during it, and relies solely upon the trained horse. Ike and Kahn were the only two trained, I want to say in 2007 they started training a third horse.
They used to run the Headless Horseman through the campfire program Halloween night, but I haven't seen that done since Equity took over the campfire sing a long. It's nice to see they have him in the golf cart parade. And I know he was a major part of the Haunted Hay Ride story.
