Being a ninja in Miami is hard. Not only is it really hot under that black uniform and mask, but there are hardly any tall buildings to scale. And even when you find one, everyone assumes you're another MMA fighter acting like an asshole. So where do you go when you're a master in the art of stealth and seeking a supportive community of like-minded ninjutsu practitioners who understand your struggles? A strip mall in west Miami, of course. That's where you'll find MAC Sports Supplies, a small mom-and-pop shop owned by martial arts experts who are more than willing to offer an open ear and an array of numchucks, swords, hand claws, ninja garb, and other training gear at reasonable prices. We would tell you where it is, but you'll just have to use your espionage skills. What, the address is listed above? You're good, ninja, you're good.
