Have you guys all seen the Hardiness zone map put out by the Arbor Day organization? The USDA normally updates the hardiness zone map every 15 years but hasn't done so since 1990. The Arbor Day org used the same data the USDA uses to complie the maps and made their own since the USDA hasn't. They have the new map, the old map and a map showing the changes. Here are a few pitures of the maps. You can also get them at arborday.org. Tell us how your weather seems different than it was 10, 20, 30 years or more ago.
