We have a club at my school. Not specifically a jits club, but a martial arts club. It started a few years ago, before I was around, as an MMA club. Over the past couple years, it has evolved into a pretty serious thing. Our classes range from 3-4 people to as many as 15 or 20 at times. We have a BJJ blue belt that runs the jits, and a 4th degree TKD master that runs TKD. We also do some muay thai, hapkido, wing chun, and wrestling. We have classes 7 days a week now and there are 3 or 4 of us that teach. The school has some wrestling mats (not the best, but sure better than a gym floor), a couple of heavy bags, and some mits and pads. It's not an "official" club, but we do have quite a bit of involvement.
