My husband and two sons take BJJ. Sons have been in one in-house tournament. Their instructor is brown belt and a ref for NAGA. We all take TKD also. Our TKD teacher is a sponsored BJJ athlete, so we learn a lot of BJJ in there as well. Husband comes home drenched in sweat, his gi drenched, and bruises from 90 minute BJJ class. There's no women in there, so I'll stick to TKD (at least there is another woman for when we do BJJ stuff).
I can't wait for my two sons to be in another tournament. Next time NAGA rolls around.
