The next jam was the most common wildlife traffic snarl in Yellowstone: bison. Bison are huge and ubiquitous. Husband Brad calls them rattalos because they are everywhere! A calf approached our car very directly. While I was composing a shot, I found out that bison are not as doped up as they look. A huge, male bull shrieked a bellow at the calf and shook its black tongue at me. Thought I was going to need bear spray.
Eleven hours later, we still had seen no bears other than that smudge in the field. No more elk, no moose, big horn sheep, mule deer or antelope. Other than bison, we saw chipmunks, squirrels, Canadian Geese and a vole, which is like a mole, only Northwestern. After eleven hours, we were beat. Honestly, as we headed back to Old Faithful Inn, it would have taken a big horn sheep riding a bear to get us to stop.
