I started Civil War reenacting when I was in the 8th grade, my social studies teacher and math teacher were big into it. We had before school clubs that we could join and they had a Civil War club. I was a new kid at the school that year, having moved from Kansas to Nebraska the summer before. I signed up for it. I know it seems like a really odd thing to do, but I feel in love with history because of those two guys.
I reenacted from 13 all the way up to 33, when the group I was part of was absorbed by another group that was a little to hardcore about it all. I still do some living history work with the museum here in my hometown and the one in the next big town over.
To answer your question if I smoke my pipes when I am involved with the living history side of things, it depends. If it is an event that it would be appropriate for me to do so, I do. If it is demonstrating something for a group of school age kids, no.
