While we were driving around Yellowstone, we ran into a heard of Bison and got stuck in the road for about 20 minutes behind them! It was pretty up close and personal. They passed within inches of our car!
We were also lucky enough to see some mountain goats fighting in one of the pullouts! They were about 30 feet from us! Very Cool!
This was one of my favorite days of the trip. Right up my alley...I only wish we had time to stay longer and do a few hikes!
