The Bunny Man is an urban legend that originated in Fairfax County, Virgina, in 1904, however in the 1970's the terrifying tale began to spread throughout Washington, D.C., and even into Maryland. The Legen has many variations; most involve a man wearing a rabbit costume who attacks people with an axe or hatchet.
Most of the stories occur around Colchester Overpass, a Southern Railway overpass spanning Colchester Road near Clifton, Virginia, which is why that bridge is referred to as "Bunny Man Bridge"
Versions of the legend vary on some elements such as his identity, motives, weapons, victims, description of the bunny costume or lack thereof (some stories he wears bunny ears and nothing else).
It seems the best time to encounter the bipedal hatchet wielding bunny is on Halloween. It is said that is the day the Bunny Man died and is aging specter is said to once again hunt the woods of Clifton in search of new victims.
