Kudos to John Roy for writing this piece! There is also a mention in the article of Luke Gygax's panel, Growing Up Gygax, at Gary Con XI in March. I will be there possibly because I'm also in a panel at the con, Celebrating Greyhawk: A Fandom Renaissance which is right AFTER Luke's. Come see me along with Anna Meyer, Bryan Blumklotz, Carlos Lising, Kristoph Nolan and Allan Grohe. Hopefully we get some spill over from the Gygax panel to talk more Hawk!
Update 06/24/2021: Removed old convention links. Needless to say Gary Con XI was a blast and if not for COVID we would have done it again.
