Tornado-loving BB pal Jody Radzik just turned me on to Extreme Instability, a collection of one intrepid storm chaser's breathtaking weather photography. The above photo that I've taken it upon myself to title "Act of God" is from a bow echo in Watertown, South Dakota on August 3. The photographer: "I'm driving along, having gained at least a small bit of ground again, when I see this white cross and a roadside chapel next to the road. No way. Slam on the brakes, pull over and jump out of the car and shoot fast fast." Extreme Instability
