LAWRENCE, Kan. (AP) _ Some bar owners are being caught by surprise by a 2007 law change that allows concealed-carry permit holders to bring loaded guns into drinking establishments.

Lawmakers made changes to the original 2006 law last year, removing language that flatly banned permit holders from bringing firearms into bars.

But few members of the hospitality industry were aware of the change, or the fact they may have been serving armed customers for a year.

Bar owners wanting to keep guns out of their businesses must post a sign saying the weapons aren't allowed.

The law still makes it illegal for permit holders to possess a weapon when their blood alcohol level is greater that 0.08 percent, the same as drunk driving. Also, people without a permit still can't carry a gun into a bar.
