West Virginia to DC?  My growing season is four to six weeks longer than my next door neighbor a hundred yards down the hill. In fall when the first few frosts hit and the grass turns white in the morning, there is a line just about at my property line. And in spring my ground is clear while his is still covered with snow. I have not seen a zone map that differentiates between Tom's yard and mine.
 
But it gets better. The map puts me in USDA Zone 5. But microclimates in my yard run from Zone 4 to at least Zone 7, possibly 8 with a little help. That's why I don't put a lot of emphasis on zone maps. And that's why I've done several columns over the years on how to explore your property and identify the different microclimates. I don't know whether any of my readers have actually done it.
