I just came home from work im so tired i work in a park doing reenactment of the American Civil war!
So you are an American Civil War hobbyist is it? I know a lot about it. They are called living historians. 
That is me! i felt super special but realised that they do reenactments in Canada also!
Yes not only in the US and Canada but there are also reenactors doing it in Europe in countries like the UK and Germany.
But is it not about me i heard from my boss that Civil War veterans recreated battles as a way to remember their fallen comrades
Yes and they also wanted to teach people about the Civil War and what it was really about. It's a good learning process.
But we also need to be very carefull because In 1998, a re-enactor at a Battle of Gettysburg recreation borrowed a handgun that contained a "squib" and shoot another re-enactor in the neck!
I guess it can be risky if something like that happens, and since it grew in popularity during the 80's and 90's it's probably more likely something dangerous could happen.
