Class A First-hand BFRO #3421

Family has unusual experience outside Grass Valley

June 1978 about 9:00 at night Grass Valley, Nevada County, California 10 witnesses

Account

A group gathered around a late-night bonfire at a rural ranch heard an extremely loud screeching howl from a nearby canyon and heard brush breaking as something large approached. The group fled to the house, and the witness briefly left her young child outside before going back to retrieve her. The child later said a very big, very hairy figure walked up to her, looked at her, and then walked away.
