And furthermore, the USDA zone system is only useful in determining
whether a particular perennial plant will survive the typical winter
extreme lows of a region.  These zones are of no value whatsoever in
planning the annual vegetable garden.  That's why I include my climate
type in my sig, rather than my USDA zone.  My USDA zone here in the
foothills of the Cascade Mountains in NW Washington state is the same as
that of southern Tennessee.  I've lived both places.  It ain't the same,
let me assure you!
