I'm not sure. My wife is Shawnee, and while you would think that would make here MORE likely to get into history, I guess the fact that her people kind of got screwed out of everything that they ever knew in Lafayette makes her not so keen on attending.

I've been trying to get her to go to that event for about three years now, and we never seem to make it. The year that I attended (a long time ago!) they had a game of lacrosse going on played in native garb. No one got their arm broken or anything, so it wasn't as authentic as it could have been (that's a joke!), but it was neat to see. Lots of vendors and friendly people who like to talk.
I convinced her to go to Blue Licks Battlefield with me over the summer and see the spot where her G-G-G-G-G- Grandfather killed my G-G-G-G-G-Grandfather, but that (combined with living in the woods with me for a month) is probably about as much frontier history as I'll be able to squeeze out of her in a year.
Is that big event the Pennsic War? I was reading on SCA.org about that. I'm not much on the whole chivalry, following orders, serving the king, angle- ACW reenacting broke me of that. I'd like to do some barbarian horde reenacting, personally. I've been reading about the Celts, the Franks, and the Vikings. I made a sling last night and went out in the back yard with my sons to hurl a hackey sack at each other with it. Wicked fun. Check out
