there is a judo club in farmington hills that has some AMAZING guys...
[USJF] United States Judo Federation, Neil Simon the president of the united states judo federation runs it. There is a guy there who is like 425 years old that will wreck you...its comical (and in due fairness, hes 60 at worst, but he looks like somebody out of a movie about judo, its great). Look into it. They take judo very seriously and still train it old school with discipline and flow at the heart of judo and all, so as long as you don't mind certain traditional rules, you'll have a great time...also, they charge nearly nothing so thats a perk
