I had an interesting chat to one manager at an airfield I used to visit frequently but no longer do. I quickly realised that high viz aprons are not for safety at all but rather so management can spy on people walking around the airfield. I said so what. His response was that he doesn't want just anyone strolling around and looking into someone else's aeroplane. He wants to easily see who is on his airfield when he looks out of his office window. As far as security is concerned, he couldn't care less if it keeps people away. He has a waiting list for hangarage and outdoor tie-downs. He's unconcerned that people don't visit the airfield any longer. If they do they can stand behind the high fencing an observe what is going on.
That's the sort of attitude that will kill it for aviators and enthusiasts. The airfield is not in the UK by the way.
