| I knew where most of the first numbers were, but like transplant I got thrown that Montana and the Dakotas begin with "5". I knew the Texas/LA/AR area began with "7", but thought the "5"s didn't go that far west, especially since Illinois is a "6". It still took me awhile to get Springfield. I knew Chicago was "606", so was thinking a lower "6" zipcode for Sprinfield.. |
