I learned how to use nunchaku as well as several other "dangerous" martial arts weapons when I was in high school. When I was in college, my summer job for a couple of years was night watchman at Barry Farms swimming pool. For those of you who might not be familiar with "the Farms" I can only tell you that people thought I was crazy to ride my bike over there every night for a minimum wage job. It was, and is, a tough place. On a hot summer night a dip in the pool was quite a treat. My job? Keep the wannabe Mark Spitzs out of the pool. Wonderful job, right? In order to develop a little rep and keep the brotha's cool I would perform my nunchaku ritual prior to going on duty at night. I would stand by the pool working out with two sets of nunchaku. Every now and then I would bring a Shuriken (throwing star) and practice using a piece of styrofoam or a box as a target.
The fellas must have thought I was the second coming of Bruce Lee because for some reason, I never had any problem with unauthorized activity at the pool....of course this was 30+ years ago before Barry Farms was fully armed. I wouldn't even bother now...
