As a vendor, sales were amazing. While I do have some competition on cosplay grade swords, I'm the only one with both functional replicas and actual antiques. There are, in fact buyers for such at an event of this magnitude.
As a writer, I saw an upcoming anthology that listed my name right below David Drake's, and I was on a panel about "Real SF for Writers" that involved me, Timothy Zahn, Larry Niven and Jerry Pournelle.  I can only hope that some day all of this will pay off to being a "real" writer who can dare to hope to be invited to literary conventions.
Both girlfriends were with me, and someone not clear on what that meant asked me, "Isn't that dangerous if they meet?" No, not at all, since we were all in the same room. How does that work, you ask?  Wonderfully. Thanks for asking.
There were some amazing cosplays, including Teenage Mutant Stormtrooper Turtles with kilts, a Deadpool/Assassin's Creed/Jedi mashup, and someone doing a great Randy Savage outfit.
I tried some new to me Scotches.
Off site, I got to show off my cape gun and a Lefaucheux 12mm pinfire to several writers who also share an interest in firearms.
There was a mass signing for Black Tide Rising, AND for Forged in Blood. The latter with myself, Larry Correia, Mike Massa, Chris Smith an Kacey Ezell.
I may have a paid interview gig on SF for another outlet.
The drive back wasn't too bad on top of that.
No food poisoning this year.
Already booked for next year.
