In recent years the KOI has been done on a military facility. At one time the gate was always open; just check in at the fire station. Today, after 911, it is an AMA membership, club membership, sanctioned club & flying field, back round check, legal waivers signed, submit a form a week prior for permission to use the field, then approval from the legal dept. & NAV-OPS, then a code that changes monthly to open the gate, call NAV-OPS to tell them you are going in & when you leave that the field is secure. Simple, no sweat!
