Ninjitsu websites that are just cool. Heres one Vintage Ninja , has alot of neat cinema and culture related fun stuff . http://vintageninja.net/
I've been frequenting vintageninja for years, the guy is a wealth of information about old ninja movies, and the 80's ninja boom (Lustbader, Sho Kosugi, Chuck Norris, Sonny Chiba, Storm Shadow, Golan-Globus, collectibles, video game and martial arts ads, bootlegs, etc). Friends with him on Facebook, he's always up to something cool.
