Possibly the DUMBEST street sign ever!!!

And you KNOW some idiot did exactly that, and probably won a lawsuit, and that is why that warning exists. Jet ski maker, CYA.

that reminds me of suzuki getting sued by 2 ''drunks'' that flipped a 500 quadracer (quadzilla) trying to climb a steep hill at night . I remember it cause I used to ride one , and was good friends with the suzuki mechanic in Victorville at the time ...oh, the democrat judge ruled the the drunks favor !!
