I would have been honored and enjoyed myself as 1/3 FanGoH at any con, but I'm especially proud to be associated with DetCon1. It occurred to me that the con actively worked to include the best of the past, present, and future.
Past: The honored presence of Roger Sims and Fred Prophet, co-chairs of Detention, the 1959 Worldcon in Detroit; an excellent bunch of panels on the history of the genre(s) and of fandom, some of which supergee and/or I were part of. Our "Fat, Feminism, and Fandom" panel was around the 30th anniversary of the original panel and the 20th anniversary of the publication of Women En Large: Images of Fat Nudes, a key fat-acceptance text that grew out of the panels.
Personally, I was delighted to see fan-friends I had not seen for ten, twenty, even thirty or more years! One would think that all of us were growing older, except Nicki Lynch, who must have a portrait in her attic.
The Present: Not having been to an sf con for four years, I caught up by playing Cards Against Humanity (and a very special version, Cards Against Fandom), delighting in the steampunk wear around me, learning about authors that have been around for a while but I still need to check out.
The Renaissance Center, the scientifictional building that housed all programming, is all about both the growth of Detroit in the present and its hopes for the future.
Also, I'm especially proud to be associated with a con that provided free memberships for locals who could not afford the membership fee. While this action was especially relevant to Detroit, I hope every con does this. And this was on top of keeping the price as reasonable as possible to begin with.
The future: Most noteworthy were the positive efforts to reshape fandom for a more inclusive future, including reaching out to PoC as guests and for programming, holding a ceremony to give a YA fiction award, a healthy and attractive track of programming for children, and panels that examined where fandom is going as well as where it has been. Even that slippery-slope stalking horse, a poly marriage, for Fan GoHs, ha ha.
Another neat way the con was about the future, if not entirely deliberate: since many of the most popular writers are going to London for the Worldcon and didn't attend both, the programming was full of more up-and-coming writers that I was glad to hear about and get to know as people; their presence also provided a more diverse set of viewpoints on the panels.
Truly, fans are timebinders; but I've never seen a better example of it than DetCon1.
