Where can I find a Zones map, or other definition/specification to know what zone I'm in?

"The United States is divided into several regional hardiness zones according to the average annual minimum temperature. These regions are most commonly referred to as Northeast, Pacific Northwest, Midwest, South, Southern California, Desert Southwest, and Mountains & Plains although each region can be even further divided into more specific climate zones." Most gardening books have these maps located in the front or back. You can also find them online at: http://www.usna.usda.gov/Hardzone/ushzmap.html
