Humans Are Kinda Stupid

So I was out in San Diego a month or so ago. I was on the beach walking around doing some location scouting for a shoot the next day. Beautiful weather, amazing cliffs, and pretty damn clean. Then I saw this sign warning visitors about the hazards of diving head first into the surf. Who the fuck made the decision to have this sign designed, made, and eventually screwed up onto a piece of wood?.......
Just another explanation of why humans are some really stupid creatures........
