In the last week of August 2013, these bison were racing along the Yellowstone River in the Hayden Valley of Yellowstone National Park, enjoying the warm weather. The third bison, the one in back, quickly dropped out of the race. I entered another photo of this bison race in the Official Federal Recreation Lands 2013 Photo Contest. Click on these links to see my entries (and vote, if you would be so kind!) and also learn about the contest. Photographs taken on America’s federal lands, national parks and historical sites from Jan. 1, 2011, through Dec. 31, 2013, are eligible. Did I mention there were prizes! If you enter the contest, be sure to put the link to your photos in the comment section.
