Interesting about the IMC - I'll ask. One slight problem with asking 'them' is however helpful they are (and they have been, without exception) every time I call (or visit) I get a different answer. LASORS isn't the cure, either.
The lifetime PPL is a dark area. My original was issued in 1966 and they've junked their records, assuming, I guess, we've all gone to seed. I'll persist.
