What happened to all of the campaign signs in Millburn?

I was drving on Wyoming Ave. this morning on my way to Shoprite and noticed that almost all of the campaign signs had been removed. There had been a lot of them. What happened to them?

eta - It wasn't as if some signs were taken by the opposition - all signs had been removed. In some cases houses had several signs. 

I think there are some Millburn residents who are on this board. @bub?
