When you pull up next to a buffalo, you can feel your breath catch in you chest. The animals are magnificent. They look cuddly and docile, with their shaggy coats and big puppy eyes. You might feel the urge to get out of your car, give the great beast a pat, or maybe snap a selfie.
Resist the urge. I repeat, resist the urge.
Every year there are people gored to death in the national parks because they approach a buffalo.
Last summer when we were in South Dakota, we were driving through Wind Cave National Park when we saw the bison herd. We pulled over to watch them for a while. And we were shocked to see a woman actually get out of her car, saunter across the field to where a large bull was resting, and she pulled out her phone to snap a selfie. Just don't do it.
I'm sure you heard about the tourists who tried to "rescue" a baby buffalo in Yellowstone. If you want another perspective on the whole thing, read this Washington Post article.
Above all else, respect the wildlife. Don't approach them. They live there, and you are just visiting.
