Hats are important! In addition to protecting you from sunstroke and waterblindness the shadow caused by the bill (or brim) can effectively hide your face when you have a photograph taken of yourself holding your most recent lunker! Additionally, Baseball caps can be worn in 3 positions: ON (Bill of cap pointing forward). OFF (Bill of cap jutting out over right ear.) And LOCK (Bill of cap in between above 2 positions. Lefthanders wear them just the opposite.
