I had the pleasure of playing with him, his son Ernie, Arenson, and others at several cons and minicons in and around Lake Geneva where it all started. I was in high school, playing the game with it's creator... man it was something else. Somewhere in one of my garages I have a first edition Player's Handbook, DMG, and Monster Manual signed by him. Worth nothing I'm sure, but a keepsake from fun times.
Edit typo Arneson
