It's the greatest zip code for the greatest city in the world. It's the windy city, the second city that's first in everything, and the true center of the universe. It's Chi-Town and if you're from there you have every reason to be proud. Chicago is the home of Playboy, Wheaties and the Second City comedy group. Your town survived a huge fire and paints the river green on St. Patty's Day. You've got it all, Chicago, and now you even have a great tee to celebrate you.
