Or, as I like to call it, Amish spam. (Sorry Amish).
I'm not talking about for sale/for rent signs in the rights-of-way, although there is plenty of that around here (and one guy that actually spams by putting the signs in the ROWs of properties he doesn't rent. Sleaze-bucket.) And I'm not really talking about yard signs where there's a connection between the resident and the event. I'm not talking about political signs, or lost kitten/puppy signs.
I'm talking about the Dating/Singles signs. The 'We Buy Houses' signs. The small businesses that think there's nothing wrong with using the collective property of the citizens to promote their businesses. Roofers, salons, blacktoppers, computer companies, crane rental services (!), builders, restaurants, tax preparation services, you name it. Gracious, there's even a church that has created it's own wayfinding sign system (nice metal signs, too) that have plunked them down all over downtown!
This crud has become epidemic here. Right now, our codes are so ancient, it would take a rewrite of some significance to address it, and there's little legislative will. Doing some research for the re-write I cam across Citizens Against Ugly Street Spam. I can't vouch for the site, but it seems to have some resources that may be useful.
So, has street spam become a pandemic?
