Wayne Canter sees a weather pattern: "I live in Perry Hall ... When there is a line of thunderstorms approaching, they either fall apart or split apart just before reaching Perry Hall, only to re-energize after leaving the area." He asks if I have a theory to explain it. I do. It's the "New Seed Theorem." Someone has planted a lawn in Perry Hall, and this is his inevitable punishment: No rain. It's a corollary to the "Clean Car Law." Wash your car, and it will rain.
