RE: How to handle a difficult pilot!
I could show up at that field any time I like and fly without showing my AMA card. I'll even invite all my non-AMA friends to join me. We'll fly there every day just like we own the place.........until one day a County agent walks up while we're flying, along with the Sheriff and we are asked to show proof of AMA.
I'm not sure how the rest of this scene would play out, but I am sure that in the future the same set of guys won't show up to fly there again without their cards.
