A Yellowstone Traffic Jam

I was on the lookout for bears, elk, wolves, antelope, and bison. I saw antelope on the way to the park, usually a bit too distant for a good photograph. If they were close enough, we were going too fast to get the photo. We didn't see any bears or elk. We might have seen a wolf - we couldn't be certain whether it was a wolf or a coyote. The color appeared a bit light to be a wolf, but it didn't seem scruffy enough to be a coyote. But what we did see plenty of was bison. They are just about everywhere except in the canyons. You can see their footprints all around the geysers and hot springs. (All the places where humans are warned to stay on the path.) Clearly they don't fear those warning signs. They are responsible for most of the traffic jams in the park. The speed limit in the park never exceeds 45 mph. Safer for everyone. But when people see bison, either in herds or one or two along the road, they stop. Most of the folks who are stopped are taking photos. Eventually the traffic moves. However, if one or more bison decide to get in the road, everything stops. It stops until they decide to move. If it's an entire herd crossing the road you could be in for a wait. They have the right of way and they don't seem to be afraid of people or cars.
