Ripp,

One hears about guys hunting tame farmed bison. Your neighbours might be ranch raised. But sounds like the meanest of the bunch. Ripped and cut by barbed wire would not have improved his mood. In any case it wasn't a proper hunt. It was dealing with a nuisance angry animal. Still some fun.

I can readily see how animals might not associate horse riders with humans. Same was where back if bakkie "hunters" do not shoot from vehicles. In a vehicle a person can get closer than on foot. Not associated with a human threat.

Back to bison. From my limited experience on some 24 bovines, mostly water buffalo, a cape, a banteng, the rest scrub bulls, the scrub bulls are the most aggressive, most likely to charge. Not necessarily as hard to put down as some others. A scrub bull is probably define as a bull born to a domestic cattle herd, or from cattle originally from such a herd, where the bull has probably never been handled by humans. Evidence might be their horns have never been lopped off. Some might say these bills care "tame milk cows". They have never hunted them.

I rate scrub bulls as top bloody exciting hunting. At times. When they come bellowing down the hill looking for ultra violence.
