George Braly has the patience of Job, and must have a very stable source of funding to support his 12 year (and counting) crusade. GAMI’s efforts are fueled by business decisions; they hope to be the first to find the giant pot of gold at the end of the rainbow. That pot of gold will be filled by you and me and everyone else who pays even more for G100UL than we are now paying for 100LL. So while George seems like a great guy and I respect his dedication, I am personally in no rush for even more expensive avgas.
