I was fortunate to have met John Deakin at OSH circa 1999.
Someone set up an area for Avsig types to congregate, Doctor Brent Blue hoisted a plucked chicken but no bbq as plastic is tough to chew.
Walter from Louisiana was there with his Beech 18, still with roundies and tailwheel but IIRC single-pieced windshield, I forget if tail was original or single
Probably Braly too but he’d have been busy at a booth much of the time.
Braley, Deakin, and Walter were running pilot training seminars our of GAMI at one time. ‘Lean of peak’ operation no doubt included.
John wrote at least one book. https://www.advancedpilot.com/apsstore.html, IIRC a second was less formal.
