Interesting chat packs. They are really brilliant for starting discussions and getting to know about people.
Anyway, I don't know why, but I have always loved the idea of combining relay races with combat or martial arts. It may look weird or ridiculous but I want to experience a situation where there is some actual struggle and fighting before getting to the finishing line. I really do prefer to see rough and tough races.
That's a great idea; I'd love to see it!
