I am curious to know what the security policy is at other elementary schools out there. At my school parents can pretty much wander freely as long as they've signed in and gotten a visitor's pass. The official policy in our handbook is that they should not just "drop in" when they need to speak to a teacher, but should make an appointment. Of course many don't follow that rule. Also, does your elementary school have a security guard? We don't, and I wish we did.
