If you see bison on the road, be patient and stay in your vehicle. Wait for them to move, and do not honk your horn. That will only make them go slower. A bison’s level of aggressiveness, both physical and passive, is legendary.
Sharing the landscape with bison requires a sense of awareness more than anything else. Bison do not pose a threat to people unless you get too close. Many bison-related injuries in parks result from people approaching them to take a picture or when people ask them “What did the buffalo say when his son left for college?” “Bison!”
Instead, use a camera with a telephoto lens to take photos from more than 25 yards away. Also, if the bison happens to park itself in an actual parking spot, honking will only result in you both sitting there until one of you grows wings.
