Theres a huge bison ranch in a small town called Florence Colorado thats fenced off . There are signs posted all over the place warning people not to stop and mess with them. The stupid tourists are always stopping to take selfies. Theyre magnificent beasts and be respected.
Once we were moving across an open area in deuce and a half trucks. Several of the bison decided to chase us. Since we were driving over open ground, you just couldn't speed up. The bison seemed determined to push us into bad terrain. One of the drivers, let a bison get too close, then he hit the breaks. The bison rammed the truck and fell down stunned. The whole herd broke contact after that and let us do what we wanted.
Bison aren't stupid, you just have to show them where they stand on the food chain.
Bison have bad eyesight.
They have bad eyesight and tend to view everything that gets too close to them as a threat.
