This event was hosted by the Slaughter County Roller Vixens.  I'm a bit confused by the three versions of this patch.  One is black and white striped, obviously for referees.  This one is pink, perhaps for NSOs.  Why is there a third version in red?   I have no idea.  But it does say "official" on the patch.  At first I thought the red and pink patches were the same except for different lighting, but the red one has a white gun, whereas the pink one has a pink gun.  That's not lighting.  So I have no idea why three officiating versions.
