Events certainly change perspectives.
Prior to 11Sept01, the folks at the airport where I keep my private aeroplane were dead set against ANY type of security. About six months ago the airport administration sent a circular around to all tenents asking if enhanced security was desired...87% said YES.
The (higher) perimeter fencing with razor wire starts going up tomorrow. The police have regular patrols, day and night as there is a sub-station right next to the field. In addition, the city is thinking of hiring a nighttime security guard.
About three years ago found someone trying to jimmy the lock on my hangar...had him arrested on the spot. He spent six months in the county jail courtesy of the meanest sheriff in Arizona.
