In the Confederate camp I ran across this group who were packing gunpowder into small white paper cylinders. The fellow sitting in the center was always working an angle. For instance he wanted to charge me for the right to do the sketch. He would run the same scam any time any other 21st century tourist would wander by with a camera. He wanted to charge me more than he was charging people for photos since “We have to pose so much longer for you”. I mentioned that no one was actually posing, everyone was moving about as usual, just doing their thing. He never did collect any money, besides my currency would have been useless in the Confederated States.
A suspicion I have about reenactors is that they never die until they run out of ammunition. If you are going to take all this care to pack your charges, well then you had better get the pleasure of firing them all off.
