WOW!
I agree that's it's mostly for fun, though I must say here in Toronto (I forget the SCA name) it's inhabited by ancient studies students and European Medieval Martial Arts guys. A real fun bunch who, despite their actual archeaological pursuits, are really there just to have fun.
That's an awesome picture, if I may say so, sir.
I have one from my only SCA event. It's terrible, yet funny......
The fellow n the right is a professor of something archeological. He also instructs broadsword fighting and rides to events on a harley with a REAL viking type sword across the handlebars. Awesome people.
