Several years ago we went into Yellowstone on opening day, after a long winter, and I was hoping to see some of the herds of elk that one sees so often in shows about Yellowstone. We didn't see a single Elk. We saw lots of Buffalo and one Black bear and that was about it. I was told that wolves had run the Elk out of Yellowstone. Don't know if that was true or not but there were no Elk to see and we were very disappointed.
