It's a tale as old as time, or at least as old as Yellowstone National Park: tourist thinks bison are cute, gets too close. We're running out of ways to describe it. Frankly, we may need to come up with some new words.
Granted, someone filmed this video years ago, but it may as well be now (except that now we have thousands more tourists in the park every year).
The lady filming, who happens to offer her own acerbic narration of the events, is sitting in her car on the shoulder of the road, filming the bison munching grass from a respectful distance. Then some youths (girls too, who, as everyone knows, are usually a little wiser than boys) walk right up to the side of the road to get some snaps of the bison.
