I don't think people are avoiding flying into flyins because they are not doing the right thing.
It's more the case of they don't want to get dicked around by crasha. It's a bit of a joke really, I mean you don't see police pulling cars over after a trip checking to see if the driver is carrying maps.
If a pilot manages to get him or herself to a flyin 400 nm away in one piece from their departure point, who gives a toss how he/she worked out how to navigate to there.
