Letter Re: A Gardening Zone Mapping Tool

Sir,
 
I am interested in moving to the American Redoubt. As an avid gardener, I am looking for the most promising areas in terms of zone and eco-climate. While trying to find a detailed agricultural plant zone map of the United States, I stumbled upon this site: PlantMaps.com

 When I checking a listing for a property, I can enter the zip code and the site provides significant climate information about that specific location including precipitation levels per month, drought index, average temps as well as a wealth of area maps.  It is easy to discern the effect of elevation on those factors.  For those like me interested in growing our own food, it is a wonderful site!

Thank you, – Pamela B.
