RD, I don't think your actions were at all out of the norm. I see people wandering around airports with cameras all the time, and a handheld GPS can easily be mistaken for a cell phone, which everyone has these days. Granted the gate shouldn't have been open, but at small airports there just isn't the money for professional security, nor really the need for it. How much damage can a terrorist do with a C172? We're badly over-reacting, and need to get on with our lives.
