Bison vs. Griz
This is what everybody was watching in the previous photo - a juvenile grizzly bear pissin' off a 2500 lb bison. The rangers knew this bear - a two year old who's mama just kicked out to fend for himself.
The bear's behavior seemed fun -sure was entraining. The rangers had a tough job - and they did it wonderfully. They are supposed to keep both critter and gawker safe, anticipate kooky traffic stunts, ensure the distance between bear and people is adequate, and allow the public to witness and experience the wildlife.
NOT an easy task, preformed superbly.
