Even if you're going to this con just for HS things (which you might be slightly late for the biggest hype of the fandom for that...), you should still find plenty to do. There are at least two unofficial meetups I know of (an unofficial meetup and Dinnerstuck), and Homestucks in this area have historically been pretty accepting of new Homestucks, but also historically cliqueish enough that you should be able to find a group of them off on their own that you can join and hang out with.
If you see me at all, feel free to say hello! I'll only be doing the HS thing on Sunday (Condesce and Ballgown Roxy) and Saturday evening (something easy, probably Mom, /maybe/ a fancy Rose depending on how I feel), but I'll be carrying my Midnight Crew bag all weekend. I also carry a few emergency cosplay supplies at most times, including emergency body paint supplies (paint, setting spray, remover wipes), so if you have any issues and can track me down, I can help take care of you.
