Day 9: Mud Volcanoes (Yellowstone,WY)

(Due to lack of Internets in the Yellowstone area, Some of these posts are a little tardy)

So if you've been to Yellowstone National Park, you have probably seen the signs warning tourists to not approach the bison, as they can be "unpredictable." But they don't really tell you what to do if the bison approach YOU, nor do they have any suggestions for when the bison herd decides to, oh...wander into the middle of traffic!

The photos here are taken at the entrance to the mud volcanoes--I took them from the safety of my car. No zoom lens--these guys got pretty close!
