Only this years signs? Since you are the rule maker only this years signs count. Signs left during past campaigns must be legally posted.  And the signs of those politicians that lost in the primaries how about their signs,  Shean Nasin, Brian Sullivan and many others.  Those don't count! Primary was over when? Has it been in excess of 15 days? 
.
The signs that were placed even before the primary removed and some how arrived in the horizontal position "lying" and according to your science everything is in a state of  decomposition, "rotting" are legally posted until 15 days after November's election.  Please call Allan Giffen he will surely have the answer.  

Did I contact Allan Giffen, Yes. Still awaiting a response.

Attack on Cassie Franklin, if you consider facts and attack than you are correct. Don't believe me ask her yourself before you respond or are you afraid of what she will say?

And if it is "impossible" for there to be signs "lying rotting" then I am a liar.
