How do you find the right girl (or guy)?

I personally am looking for the RIGHT girl, not just a quick get in, get wet, get out relationship. I want to know how you go about finding that ‘right’ person.

More specifically, I want a girl who likes martial arts, loves to be active, is smart, and can take a hit (for non-abusive reasons, hehehe. I’m talking like in a jiu-jitsu match or something). I have checked in on all the jiu-jitsu, judo, ken-do, and mui-ti clubs at my college, but no girls. Where else should I look?
