Unless:
A) They are doing security checks at the door, or
B) The gunbuster sign carries the power of law in your state
I would carry anyway....just my opinion
I'm the same with "dark" In Ohio you can carry but has to be unloaded and a strip tie inserted.
I always carry.....for once don't ask don't tell. means something
Would a strap placed on your unloaded pistol prevent you from breaking said strap and inserting the loaded magazine from your other pocket? It would slow down your response, but it would be better than nothing...
If they are tie wrapping, I'd question whether the tie wrap can be broken without dikes or a knife. Those things are pretty durable.
