If I read QDM3 correctly, he is talking about strip owners who have arranged a pre-ordained event. They'd have mown the grass, shot the rabbits and might even have rolled the runway and taxiways in advance. Even better, they lay on catering and toilets for visitors.
The problem is not just flying visitors, but also twitchers who want to see the aircraft.
If the strip owner has done all that is reasonably required, I don't see why they should need to pay the insurance premium. As I recall, most, if not all of the events require a PPR and a briefing is given on the day. What more do incoming fliers want?
