In the town of Lincoln, in the US state of Massachusetts, off Old Sudbury Road, is a patch of deserted farmland where people keep mysteriously leaving old rocking horses. Some are made of wood, some plastic with rusted springs and broken legs. The first horse is believed to have appeared in 2010, when two kids put up a lemonade stand to make a quick buck in the summer. The kids went away but left the horses behind. Others say that it started with a single headless horseman that was put up as part of a Halloween show. In any case, the first horse began attracting others and the collection grew. By the most recent count, there were 42.
