Tickets for spelling errors on signs

In addition to tickets for complaining about cold weather, I'm gonna make up some tickets for public punctuation/spelling/grammar errors. We can sit here and complain all we want about how public signs have silly errors (which is always fun), but let's actually do something about it by notifying those who made the signs that they screwed up. The tickets could be either handed to the store owner, or just taped onto the offending sign.

Now I just need a list of places in Chicago that have spelling errors, punctuation errors, and bad grammar.
