Close to where I live is steep (as in STEEP), narrow (as in barely room for your car in the lane you are driving in) and winding (as in I'll get carsick if I'm in the backseat) road that attracts crazy masochists bicyclists who are unencumbered with concern for their personal safety. So the city helpfully installed this warning sign for them.
It must mean Try This!, right?
After driving past the sign for a few days, it occurred to me that maybe it was installed incorrectly. Perhaps hanging the sign this way, indicating Look Up at the Sky And Offer Your Bike to the Cycling Gods if You Make it Down the Hill Alive is what they meant instead?
I guess no one was really sure, because now that sign has been replaced with this.
