I just figured if anyone was interested they would look it up. SCA stands for Society for Creative Anachronism. Which is just a fancy way of saying a huge group of role-playing nerds who reenact medieval and renaissance life. Mostly it's a bunch of guys in armor with wooden sticks beating the hell out of each other (my husband), but there are also pirates (I'm a gunner on our ship), vikings, seamstresses, belly dancers, bards, and a lot more. Look up pennsic war on youtube for some videos to show you the gist of it.
