Many of the businesses that will be posting signs are doing it because of it is their right under Wisconsin law. As responsible gun owners we should respect their rights, just as we want others to respect ours. Pain it the butt to go back and remove your carry weapon? Sure, but I'm hoping as the folks get more familiar with the law and more comfortable with law abiding folks carrying more and more of these signs will be coming down. Folks just need to realize that they are safer with honest citizens carrying than they are with just the bad guys carrying.
If I have to return to my car to remove my weapon, I will keep it on, then go somewhere else. I may remove it, then go talk to the manager. My words will be something to this nature. I will return to your store if and when I hear you've come to your senses. I wall also tell all my friends, you want to deny my right to self protection. When he/she sees a drop in sales that can't explained any other way, those signs will come down.
I don't have my permit-----yet.(Application sent 11-2-11) But, I've been looking for the signs so I can go somewhere else. Gonna make up some no guns, no money business cards.
