In my neighborhood growing up, there was a group of friends (separate from mine), who would dress up like ninjas and roam the town. I am not sure why or what they did. (Solve Crimes?) I was also unsure as to where they got their great gear. I has always assumed flea markets or the Ninja Supply Store, but thanks to Paxton Holley and his wonderful scans, I now know that they probably went all mail-order on their get ups.
Note: If your gonna get a pair of tabis, make sure you do not go economy. It is embarrassing to the entire clan.
