Here is a post from Ryan Adams, an ISU student on a 6 month internship at Pinehurst this summer and fall. It shows what lightning can do.
Just to give a little explanation of what happened. The lightning actually struck about 5 ft from the irrigation head and proceeded into the ground, fried the satellite box and then came back through the wires and blew the irrigation head out of the ground. Crazy, especially considering we still haven't found the nozzle or top cover to the irrigation head.
