This mysterious perfect circle of dead lawn appeared in our side yard a couple of weeks ago and led me to an internet search of Ozarks crop circles. Turns out there have been a whole bunch of UFO and Crop Circle events in the Ozarks. Determined not to join this woooo woooo crowd, I resolved to get to the root of the problem. The solution was no further away than the youngest member of our household. On the morning after the first freeze, he stomped around in a circle on the frozen grass. When the weather warmed up, the grass grew everywhere but the circle he had etched.
