I reccomend that whoever is into ninjutsu start a local ninja clan, one where you dress up in full ninja attire and just run around the streets at night testing your ninja stealth and climbing an crap. I would love to see a bunch of ninjas running around my neighbourhood, i would feel much more safe. Also, try to carry around a weapon at all times, like a katana, that way it gives you insentive NOT to get booked by the cops. hah, think of it like a DONT GET GOT game. hell i think i might start one of those...
