Oh c'mon. Doesn't every region have a "preferred" wink-wink AME where
you can go and be guaranteed to pass if you walk through the door? We
do here. A half dozen filled urine cups lined up in the cubbyhole,
unmarked as to owner. Same eye charts for decades, and if you stumble
a bit the nurse helpfully offers a suggested response. Probably will
be a rush of old guys looking for LSA planes when our preferred AME
retires.
