Yellowstone National Park is one of my most favorite places on Earth. There's a half-marathon next year, on June 11. Registration opens this year, August 22. That's this Saturday. I think some of you seasoned runners should check it out. Keep in mind, though, that YNP is at an average elevation over 8,000 feet.
