I'm from Madison, pretty new to the whole scene. Myself, and a friend of mine, we put together some small events and an annual Halloween show where we dress up and cook up a routine where we can break our lightsabers for the greater good of entertaining the locals. So far it's just us two who really get into it and we're looking to branch out and join up with more enthusiasts and attend more cons and events!
For those of you in the midwest whom are not aware of Geek.Kon, it is a great con for costuming, with excellent panels, held here in Madison just before Halloween. Costume constests, a lot of merchants and gaming on the projection screens on top of a lot of fun!
