I really like this, because it’s a pastime that’s cooperative, but seems competitive.
Choreographed light-saber duels! They’re pretty good, too.
I also like that about the worst thing you might endure is a whack in the face with a lighted plastic tube, or maybe a skinned knee. Back when I was in college, I did some viking reenactment, and that’s why I wear my mustache the way I do – it hides the scar from where I ate the edge of another guy’s shield during a routine that zigged when it was supposed to zag.
I love the level of effort they’re putting into it. And the technology looks like it’s getting pretty good, too.
