Last time I went to the PHOF, Tim was running around with his head lamp, fixing games. He didn't even look up to make eye contact when he passed us. He just went along his way, dilligently working. People who are approachable will let you know they are by their body language. It was clear to me that Tim wasn't approachable at that moment, and that's cool - it's who he is.
It was a cool to see him in his element, doing what he loves.
