Political signs

I wonder if there is a city/county (Tallahassee/Leon) ordinance covering display of political signs. Do you know anything about it?

I had a presidential campaign sign displayed in front of my home for a few days only to wake up this morning and see it missing. I hope someone took it in order to display it in his or her yard :-) I see these signs displayed in my neighborhood and I do not think I violated any ordinance covering the display any differently than my neighbors have done whose signs are still up. Of course, one obvious possibility is that someone just did not like seeing my sign and decided to take it down. But, I am looking for other explanations. It was not the wind or any other act of nature, I am fairly sure of that.

What do you think?
