The only other thing I know of, would be the Centralia Balloon Fest, and it can be preety hot during that time. But aside from Fred Bird, the STL cardinal, there's never any one in costume there (or reason to be, I once thought of asking some 501st guys to it, but theres just no one down here). So having some presence there would proboly be something for the kids. (If any show up, LOL...Its a lot of crafts and crazy people usualy.) There usualy 3 or 4 bounce arounds there as well, so its not like there's never any kids there, just a lot of older people who "won't get it".
There's just hardly anything as far as events go down here.

P.S. - I gotta think about a SW costume for this year/next Celebration....
