"Am I in a Katrina GO Zone?"

Someone just visited this site based on a search for the phrase above, and I always feel badly when people arrive here and don't see what they're looking for. So, yes, Virginia (or, anyway, yes, Gulf Coasters), I can tell you how to find out if you're in a Katrina GO Zone. Actually there are three separate GO Zone definitions for Hurricanes Katrina, Rita and Wilma. All of these are defined -- and carefully distinguished from the larger "Disaster Areas" for each -- by this section of IRS Publication 4492. If you download the whole PDF version the definitions start on Page 2.
