At 50 years old, I finally made my first trip to Wyoming.  While visiting Yellowstone National Park, more than anything, I wanted to get to see buffalo.  While the scenery itself was even more beautiful than I could have imagined, the day we were stopped on the highway by a herd of buffalo walking down the road was simply amazing.  I was able to get some great pictures of bulls, cows and calves as they walked right by the vehicle.  When I later examined the pictures, I found in the background was a fly fisherman completely oblivious to the moving herd.
