Oaks, Bloomsburg and Harrisburg have either Police or security standing at a table when you come in. Oaks actually has a clearing barrel
One time in Oaks I had IWB without a cover shirt so I went to the table , dropped my mag, cycled and cleared, then used the barrel. Police put a zip strip in.
Funny part is when I went to use the mens room the Urinal and garbage can were full of zip strips

The rest of the times I just walk up to the fine person taking donations (entrance fee) and in I go. The zip strip table looks at you, but I have never been directly asked.

I would say not to uncover your firearm or remove it while inside, unless a true need arises then prudent marksmanship is advised

I believe in CANT
