This has got to be tied to the open carry law, right?
Not to get political, but actually no. On July 1st, 2015 is when the state's open-carry law was extended to concealed carry individuals. This enabled an individual to CC without a license.
The law preventing the banning of firearms in municipalities and such unless those institutions can provide adequate security was a separate bill that went through in 2013.
At least I think that's what you were asking; please correct me if I'm wrong.
As far as the OP goes, we already have to do this for every professional sporting event or concert. My biggest concern was like most in here. How do I get my alcohol into the stadium without detection?
