I saw this very large black mass approach from the west and decided to head out with the camera. When I spotted numerous other photographers set up on the roadside with their tripods and cameras I knew something was up. There was a tornado warning! I skirted the very large storm around the south and west sides and followed it from Markerville, finding appropriate places to catch the very well-shaped cloud formations. The other photographers were just trying to catch a twister, I was trying to catch the size and nature of the storm itself with all its massive grandeur. This series of views may have done that.
