I went on this buffalo harvest/hunt last year. This has got to be the best deal around. Four hundred-some pounds of boned-out good meat. Don't let the draw scare you away. The non-trophy hunts were not sold out last year, I guess because not many people know about it. --The trophy hunts have a five-year waiting list.
The hunt is over quickly - they asked me to shoot it in the neck. There is a fence around a ~4000 acre enclosure, but at least you are on the open prairie.
