10. Civil War Re-enactments
Civil War re-enactments are kind of like the fraternal twin of Renaissance Fairs; they're historic, they're everywhere, and by god, are they geeky! Now like we said, they're everywhere, so chances are you can find one in your region, but if you want to experience the mother of all civil war re-enactments, then you might want to go to Gettysburg itself, where this July 4th, they'll be celebrating their ONE HUNDRED AND FIFTIETH CIVIL WAR REENACTMENT WITH OVER ONE THOUSAND ACTORS! That's a whole lot of muskets!
