Wildlife in Yellowstone

We saw a lot of animals in the park and were fortunate enough to get pictures of many of them like this lovely deer.
This guy could not manage to go the speed limit and backed up traffic for miles!
While we were hiking to Tall Falls we saw this mother and baby having dinner. There was another fawn that I couldn't capture because he was having too much fun leaping around in the grass ahead of mom.
This was the highlight of our trip to Yellowstone for me, we saw this mama bear and two baby's less than 50 feet from the road. They seemed completely unphased by the crowd of people taking their pictures. We saw another young bear running around on the side of the road and I snapped several picture, but they all look like big-foot sitings; indistinct and slightly blurry!
Even though we didn't get pictures of them, we saw a huge Elk our first night in the park and a Coyote that almost darted in front of our car as we were leaving the park.
