As Luke and I arrived in Yellowstone, we were stunned to see mule deer just wandering around the Mammoth Springs area. They were so close and seemed quite comfortable with people snapping hundreds of pictures of them as they causally grazed on the green grass in the small town-like setting. After this initial sighting of wildlife, Luke and I set our sights on seeing bison. All day we peered out the car windows as we traveled through the park in hopes of spotting a bison in the wild. As we left Old Faithful at the end of the day we were both slightly disappointed as our hopes of seeing a bison had diminished. However, as we were coming around the enormous Yellowstone Lake on our way to the East exit we finally saw what we had been waiting for, a large herd just soaking up the sun right off the road. There had to be close to 50 bison and even a few of their young in the group. We swiftly pulled off to the side of the road to snap a few pictures. It was the perfect way to end a great day at Yellowstone.
