"The signs are part of what WGO calls its DEFEND WISCONSIN PROGRAM, in response to the anti-gun signs being posted by some businesses around Wisconsin to prohibit concealed carry. It also aims to counter the anti-gun smear campaign of the Wisconsin Anti-Violence Effort (WAVE), the notorious Madison-based anti-gun group."
I'll have to keep an eye out for them, and make sure to frequent those places.
If you are a Wisconsin business owner and would like to put up your own signs, they are available here.
Also of note is this little bit of the article-
"Last fall, WGO launched its successful Don’t Buy List Program, which to date has listed over 800 anti-gun businesses around the state. These businesses are put on alert that gun owners will no longer patronize them until the signs are removed. To date, nearly two dozen businesses have reversed course and removed the signs, thanks to grassroots pressure from vigilant members of WGO."Keep up the good work.
