[rescue] zipcode distance calcs

[James Lockwood]

Sorry, I deleted the original message, but I wanted to mention that you
can get zip code to lat/long translation data for free from the U.S.
Census:

http://ftp.census.gov/geo/www/gazetteer/places.html

Take a look at the "Zip Code by State" file, it's comma delimited and
includes some very handy information.  Obviously you can't get a
completely accurate picture of travel time just by the distance as the
crow flies, but it may be a good enough approximation to work.
