You'd win that bet. All you've got is a piece of paper that say's "Lloyds of London" on it. I as the hypothetical CD am not an insurance agent, and I have no idea what the legalese on that paper means. Furthermore, I don't have time to read through it and make sure it's valid and up to date. I can't take your word for it because I don't know you from Adam, and you could be lying, waving a worthless piece of paper you made up on your computer in front of my face. If you have an accident, it's my kiester on the line and I'm not willing to take that risk. There are 25 people in line behind you waiting to sign in, so produce an AMA card or move along please.
Tell me this; what would the point of "opening up the door to all modelers" be? The AMA is not a charity. The AMA not only wants you to fly, they want you to join. Anything less would be unbelievably idiotic.
Bottom line here is, the AMA provides a convenient and affordable means for sanctioning competition. Ask Frank Tiano (if he doesn't bite your head clean off for speaking in his presence) the hoops he had to jump through to insure his last jet meet. It certainly wasn't as simple as filling out a couple of short forms and sending in a $20 filing fee. The purpose of this hobby is to have as much fun as possible with as little adminstrivia as possible. The AMA does a great job of taking care of all that malarchy so we can get back to doing what we wanted to do in the first place.
