Possible vocalizations outside of Elberfeld, Indiana

A group of four on dirt bikes and quads stopped at night to fix a broken chain. They heard repeated loud moans, then a series of knocks like on a tree, then something running fast through dense woods around them. Frightened, they abandoned one bike and fled, finding the bike moved off the trail when they returned the next day.
