a search shows people have been gripen about BPS's murky carry policy for years. The top brass could clear this up easy. I get the feeling there fence riding.
Been there a few times. Never seen a sign or had anyone ask about my concealed handgun. Discovery Mills on the other hand is posted. I believe that inside Bass Pro at the exit into Discovery Mills there is a sign. Hasn't concerned me at all.
