Others beside myself may be somewhat geographically challenged.
When I look at the Regional Garden headings: Mid-South, MidWest, Northeast, Northern, Ohio River Valley, Pacific Coast, Pacific Northwest, Southwest it is not clear to me which states are included in each group.
Is there some way that the headings or perhaps the first sticky in each could indicate this?
Looking online for 'US map divided into regions' yielded things like this:
FDIC's version of regions:

Drug threat regions:
http://www.justice.gov/archive/ndic/pubs11/18862/appenda.htm
So I tried the key words 'US gardening regions map' and found lots of sites who want to sell me magazine subscriptions (National Geographic, Better Homes and Gardens, and good old Sunset), but they weren't giving away examples of a map of the regions.
