I’ve been camping in Yellowstone for years now, and it never ceases to amaze me how some folks don’t seem to understand how dangerous the animals are.

This poor kid was pretty close to being stomped to death by a bison:

The family was way too close. Bison are Yellowstone’s most dangerous animals.

Rather than playing “chicken” with Yellowstone’s wildlife with your iPhone and 3x zoom camera, invest in a long lens/DSLR or a portable with a 10x optical lens. It’s much better for you and the animals. A long time ago I used to shoot with a Canon S2. That little consumer-tank with its 12x optical lens did everything (including video), and I could keep a safe distance from Yellowstone’s mighty bison. I ended up giving it to my girlfriend at the time, and she still uses it to this day.
