What should I know about historical re-enacting?

I love history. No really. I friggin’ love history. You probably will never meet anyone with as big a boner for history as the one I have.

That said, I’d like to know what you guys think about reenacting. Military history is my true forte’, and it seems like getting involved in historically accurate reenacting of the American Civil War, World War One, or World War Two would be the natural extension of my love for history. I have alot of authentic WWII and WWI gear, but other than that, I don’t even know where to begin.

Have any of you dear readers ever been involved in reenacting? Where should I look first if I’d like to give it a shot?

Opinions and banter are welcome. This is mainly in the general section because of heavier reader traffic.
