Harmony Museum will hold its annual Sleepy Hollow event Saturday, interspersing with the Zelienople library’s 100th anniversary car procession.

The event will run from 10 a.m. to 5 p.m. Saturday, with music, food, artisans, demonstrations, a petting zoo and “merchant trick-or-treating.” In addition, food trucks will serve ice cream, hot dogs and snow cones. A headless horseman is expected to ride through town in the early afternoon.

The event is sponsored by the Harmony Business Association.
