I ran into him (literally) in 2015 at an AOPA fly-in in Salinas, CA. He was wandering around by himself, and I spent maybe five minutes talking to him about 3rd class medical reform (this was before before BasicMed was codified). He was very approachable and tuned into the medical reform issue. He had become EAA chairman in 2012, and I wished him well in his EAA gig.
I was impressed; he's a nice guy.
