Datu Tim, in your younger years, did you ever participate in Dog Bros. bouts personally? I never have. Total props to those guys. About the most I can claim is "Slightly elevated consciousness through spirited but controlled contact..." Somehow it just doesn't sound as catchy. LOL
I've done some of that type of sparring with my students, but just stick fencing. I've contemplated participating at a gathering, but the timing hasn't been right. I had planned on fighting at this one, until I got hit sinus infection.
