Tourists at Custer State Park in South Dakota captured the shocking moment when a bison threw a woman back and forth, ultimately knocking her unconscious and tearing her pants off.
Incredibly, the woman was not seriously injured. In that respect she is extremely lucky. Bison can grow to a weight of 1000 pounds, and, unlike domestic cattle, is a wild animal animated by instinct.
Had the horn been an inch above or below she could have been gored.
The moral cannot be obvious: do not approach bison. They are not there for your amusement.
