Bring out the fans. The USDA has decided we're all several degrees warmer than we thought we were. Two months ago, I was in zone 6, now I'm in zone 7, having not moved an inch. They've dropped the a and b parts of the zones. I don't know whether the USDA checked with their boss about this warmer situation (didn't he deny the globe was warmer?), but they have also dropped Canada and Mexico as part of the zone map.
