Look at the two links below
This first one is a place to buy a sign.
The second one is a story about people using them.
Here is my favorite quote from the second one.
"Sara Van Allen, marketing manager for Manhattan Town Center, said the building is a family environment, and as such, the owners decided to ban concealed weapons in the entire mall.
"It's for the safety of our shoppers," Van Allen said."
Then there is this dip _hit
"Many businesses do not have the signs up, but some said the signs might be a good idea, especially businesses with a high risk of robberies, said Kelly Unekis, clerk at Dara's Fast Lane.
"It'd probably be a good idea since the law passed," Unekis said"
What the heck are they smoking????
