i once did a American Civil War reenactment,  it was really fun.  American Civil War reenactment is an effort to recreate the appearance of a particular battle
Oh yes, I've heard of those! I bet they are really fun. Do you get very detailed with your costume?
Although most common in the United States, there are also American Civil War reenactors in Canada, i like the american versions better
I think I've driven by one before. I live in Canada. I suspect Americans are more passionate in their reenactments. 
Reenacting the American Civil War began even before the real fighting had ended, which is kind of scary
And quite fascinating! Is there a feeling of community at the reenactments? Does everyone know everyone else?
im not really sure but i think they would know  the regulars, Modern reenacting is thought to have begun during the 1961–1965 Civil War Centennial
