Hi Jim,
I too am a member of CWPT and Friends Of Newtonia. I have also been a reenactor for 15 years, now adjutant/major of the 1st Missouri Battalion CSA. The current caretaker of the Ritchie is much more open to the public than th one before. I used to be Capt of the 4th Mo. and our annual elections were held there when the town has their local celebration. If you get me more info I can probably help getting reenactors to help with the filming. You can email me at shekauk@cableone.net.
