As I write this, Lexington, Kentucky, is expecting a high of 5 degrees. And tonight it’s going down to -12. If you live in North Dakota, that’s a warm spell. But in Kentucky, that’s serious cold. These people have windows in their houses—and, worse, heat pumps, which work fine if the temperature is above freezing, but not under these conditions. In a polar vortex, Kentuckians are better off huddling around a pie plate and burning dollar bills. I hate to think how this may affect the bourbon harvest.
