For the past two years, I have been testing the security theater of non-permissive environments. That is, the theme parks and other venues that prohibit firearms, even licensed weapons carriers. What I found is that most places don't do a very good job at finding weapons, legal or illegal. I have entered Disney while armed, even though they have metal detectors and bag searches, dozens of times. Likewise, the Central Florida theme parks of Universal Studios, Sea World, Discovery Cove, Lego Land, and Busch Gardens.
I was going to begin a new round of testing theme parks, but today's announcement of increased prices has placed this on the back, back burner. Now that it costs the same as buying a handgun for a family to enter a theme park for a single day, coupled with the high profile that these places have from a terrorism perspective, theme parks are no longer on the list of places I wish to be. Four people entering the park for a day, eating lunch, and leaving now costs over $600, including parking.
I will continue to enter non-permissive environments, but theme parks have simply become too expensive to continue testing them.
