Still More Yellowstone.

 Wolf or coyote?

 The only buffalo traffic jam we got stuck in.  We ended up on the suspension bridge with them.  You could feel the bridge go up and down as the bison plodded along.

 A picture of people getting awfully close to elk.

 We didn't actually STOP for an elk picture.  Everyone else was and it was annoying.
