SCA is really fun if you can get into the right group ie. one that's in line with your interests, with people you get along with. I learned how to brew beer while with a group. It's also a lot of work, as you are expected to be as authentic as possible with your costume, name, and personal history. I wish I could find time to stay with it, but that's the way it goes. I would really like to train for melee fighting. People fight with padded representations of swords, spears axes etc. and wear armor. Real armor. And they need it! People walk out with large dents everywhere.
Last melee I went to the master at arms challenged all comers during a break in the matches. No armor, one handed, just a sword. "killed" everyone easily, often with just a block and attack (reposte). Turned out he had a black belt in kendo.
