Well that depends on how much you like eating, breathing and wearing dust. I think I am still getting the dust out of my gear from the big Chickamauga event that was held there in 1999. Also with all the new homeland security concerns, it might be extremely difficult to get permission to use that site again.
If you would really like to see a Chickamauga Reenactment happen, then I would suggest you take the lead and start putting the event together yourself. Don't wait for others to do it for you.
