Unknown Heroes

Today I drove by the park and I saw some guy dressed in all black ninja gear practicing his sword skills alone in the gazebo... No Lie... In my opinion, swinging your sword around by yourself is more of a "Back yard in private" kinda thing and not so much a "Gazebo where everyone can see you thing"... However, there is a chance that he wasn't practicing, but actually defending us from invisible super ninjas... Thanks weird ninja guy, good to know you're on our side.
