This is not a bad idea.
Now we can tell from the street what stores we will NOT patronize.
Really?
I am all for conceal and carry. I am also for a business to determine whether it has the right to not permit it. Business can prohibit all kinds of activity that may be permissible elsewhere, such as speech, so why not give business owners the right (and happily abide by that) to refuse entry to those who legally conceal handguns?
I am against the government from doing it - but more power to private businesses who have the ultimate right to control their own premises.
