|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.
Posting your address in the back will also help them accurately radio the location of problems that they encounter.
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.
