Looking at the May 8 History Mystery image, which showed the collapsed John Day River bridge being repaired in the spring of 1965, Janice Byrd-Strand remembered the Christmas Flood of 1964.

“My Dad had just crossed the bridge, when in his rear view mirror he saw headlights in the pitch black dark disappear in a most unfamiliar way. Later he surmised he must have seen the vehicle that perished,” Byrd-Strand wrote.
