I just got back from visiting my sister in Atlanta. Now, she doesn't live in the city, she lives in the woods about 40 miles away. While we were there, we took the kids the the Georgia Aquarium. I couldn't take the gun due to Ohio having no reciprocity with GA, but I did take my EDC knife, which is a Boker SubCom (I love this knife) Anyway, as we were approaching, I could see that the "security" personnel were wanding people at the entrance, and I really didn't feel like walking all the way back to the car, so I put my knife in the side pocket of my wifes backpack (much to her chagrin) As I got closer, I noticed a large sign out front that read "No Guns, No Knives, and No Lighters for the protection of our guests" Really no lighters, how stupid. When we got to the front of the line, my wife opened the main compartment of her backpack to show the "security" person. He gave it a cursory glance and asked her if there was any prohibited item. She said no and he let her pass. When I went through, at the last second I remembered my keys, and removed them from my pocket and held them in my hand to show them. It was then that I realized...The metal detector wasn't even on. I looked around to the other "security" performing this screening, and none of there wands were on that I could see. Oh how I love fake @ss security to make the feel safe. I could have just as easily taken a gun in there with no problem.
Of course all of this is hypothetical and no criminal trespassing was committed.
