I totally IGNORE all such silly signs!

AND, it is NOT the same as posting your private property with NO HUNTING signs!!

We are talking about places where the public is invited in to buy whatever they might be selling. You are talking about your private property.

One local stop-n-go type gas station put up a sign that guns were not welcome and I went in and handed the owner one of the little cards explaining what I had to do get get a CCW...as compared to his customers who don't have a CCW. I explained that I would not be back as long as my sidearm was not welcome!

Next day the sign was gone......

I will not be a victim in a restaurant sitting on my hands if some nut case drops by to get even with his wife/etc.

You do whatever you feel is right. I'll carry unless it is illegal!
