I got the auto city/state lookup working.
If anyone wants to clean up this code and use it, improve it, gemmify
it, wiki it, or blog it, feel free. If you''re inclined to do so, let
me know of any improvements you make, as I might like to use them
myself.
Naturally, you''ll need a zipcode database. There''s a free one
available here:

Also, don''t forget to:
ruby script/generate Zipcode
--bryce

## hard coded javascript, because we want to change the elements''
value, not their innerHTML
$(''address_city'').value = ''<%= @where.city
