I still play with the SCA a bit, though I'm not as hardcore into as some people are. I throw axes as a hobby. I do some Middle Eastern clothing, and some ancient Roman clothing (so nice and cool for summer events) but at the moment both my friend (who got me into the SCA) and I are currently enamored with the later period garb. We're both currently working on Tudor era gowns.
I think a war bunny is pertaining to people who only go to wars like Pennsic and aren't really into the garb aspect of it? I could be way off though.
