Bison can jump a 6-7 foot fence. Or run through it. This dude is lucky not to have his entrails dragged through the park.
Used to be a herd kept above Camp Funston area at Fort Riley. In spring training one year we took some Duece-and-Halfs up there to set up a mess area in the field. One buffalo charged and rammed one of the trucks.
We gave them a wide berth after that.
