This photo taken on Dec. 7, 2012 shows bison feeding at the Buffalo Herd Overlook west of Denver. They're kept behind fences about 20 miles west of town on Interstate 70, where an overlook near Exit 254 offers great opportunities to photo the creatures with the Rocky Mountains on the horizon. Interstate 70 can be seen in the distance. (AP Photo/Ed Andrieski) less
