I met John in an Atlanta airport lounge years ago[1]. I recognized him immediately as I've always admired him, and I decided to go up to him and tell him as much. He invited me to sit down, and told him about when I was a teenager in the 90s learning about tech entrepreneurs at the time, I always thought he was pretty cool and had good ideas. I told him I respected him, and that I was sure he'd lived an incredible life and thanked him for his contributions. He was clearly totally sloshed(inebriated) and insisted he called his wife so I could recount the story to her. I did. An hr later I had to leave to catch my flight, and i asked him where he was going - he said I'd find out some "pretty crazy shit" about him next week, and that "the doc was a bunch of BS". Two days later, I read Show Time had announced "Gringo: The Dangerous Life of John McAfee". In the brief time I spent with him, I have to say he had pretty positive energy for someone who was portrayed the way he was.
