I'm co-advisor of our college's martial arts club. I've always let the students teach--usually TKD--but now they're short on instructors so I'm teaching a weekly class in arnis! It's been a great hit--they can't get enough! Unfortunately we don't have a very good training space, just a corner of the gym at the edge of the indoor track, but it's good fun. The one Filipino student is really enjoying connecting with his culture. His parents sent him rattan sticks they had!
