Hi there! Kansas Homestuck as well! In our Convention tag there are some local cons that I’ve given basic information on (I’d do more if people want me to). There are quite a few that I know of near by.
There is Anime Festival Wichita, which is in Wichita.
Motaku is an anime con in Kansas City, MO. It’s a little smaller and I’ve staffed at it before. Ahn!Con is run by the same city (different hotel though) and it’s a 17+ yaoi con.
There’s also Naka-Kon which is in Overland Park and it is a very large con and by far my favorite (and first).
I also think Planet Comicon is in KC. And there are a few Arkansas conventions, and there is Anime Nebraskon in Nebraska. Many of my Wichita and KC friends adore it.
There’s also Cosplacon that is coming up soon in Jefferson City, MO. It’s an entirely cosplay based convention and they ADORE the Homestuck fandom from the feeling I got from their staff members at other cons.
That’s all that I know of near our beloved state. If you’d like you can also check out Kansastuck’s facebook group or their cosplay group and they may be able to tell ya more. I run the tumblr page for now, but it’s not well organized or ready to be on par with the groups just yet (not until I get a co-admin, preferably someone who’s in charge over on FB).
I apologize if that’s a lot of link. Each one leads to the cons home page, or to the pages I listed specifically. I hope this helps out. :)
