The St Louis Cardinals, the Kansas City Royals, the Kansas City Chiefs and St Louis Rams successfully lobbied to make a stadium or arena that holds over 5,000 people off limits to holders of Missouri Concealed Carry Permits.
The St Louis Blues arena holds 20,000. Try calling for a Yellow Cab after a night game of the Blues. You can wind up standing on a street corner with no one around except a suspicious person. (been there, done that).
Make a wrong turn in St Louis and you may find yourself in an area with drug dealers standing on street corners 2 blocks apart.
Thank you Missouri pro sport teams.
easy...just don't go there. If enough people did that, then they'd change. f'em. They want money and I've got it.
