rondon and the dean the whole point is that nobody has been killed on a GA airfield in an accident that would have been prevented by wearing a HiViz vest. Just because somebody says do something doesn't mean that you can't apply rational thought and say No, sorry, I disagree with that. As bose x says, it's not the vests per se it's the domineering "we know what's good for you" attitude of people who are imposing needless rules which potentially diminishes respect for rules that really need to be in place.
