Class A First-hand BFRO #42140

Hiker has daylight sighting in Goodenow Grove Nature Preserve

October 2009 about 4:15 in the afternoon Beecher, Will County, Illinois 1 witness

Account

The witness was walking alone on trails at the preserve in the afternoon and heard a twig snap followed by two gorilla-like grunts near a loop trail. The witness then followed a path through tall grass toward the treeline. About 40 feet away, a brown slender entity about six feet tall was seen running silently inside the trees, grabbing a small tree while moving fast and slightly stooped. The witness walked back to the main trail without running and found only their spouse waiting.
