go up to one of them, and see how quickly they take aim for the dick. if they go for it right away, winner winner chicken dinner. i don't even know why they call it "krav maga". they should just call it "dick kick fu" quick search showed ohio krav maga with multiple locations (which you found already) and core tactix in dublin. i'm certain there are meet ups groups, and i know OSU had a lot of martial art clubs, of which, i'm sure krav maga is one. good luck!
