|Four numbers make all the difference.|
The back sides of homes all look the same, unless you happen to know which one you live in.
Police officers spend quite a bit of time in alleys and having your number posted will help them find your place should you ever need them there in a hurry.
Just the number is good. If you can add the address, even better.
You can pick up a set of numbers at no charge by visiting Alderman Tom Tunney's office or the 19th district's CAPS office.
