DEPARTMENT OF UNINTENDED CONSEQUENCES….A friend of mine tells me that some local residents where he lives complained about a dangerous stretch of road a few years ago. The city finally agreed to put in a light, which was installed two years ago. But it turned out that people didn’t know the light was there, so they just barreled on through, a situation even more dangerous than the original one. So the city installed a bunch of raised dots in the road to warn people that something was coming. This worked, but then everyone started complaining that the constant flow of cars over the dots made too much noise. So now they are building a 1000-foot sound wall to cut down the noise.

Exercise for the reader: what is the likely unintended consequence of the wall?

ANSWER: According to correspondent Ian D, the answer is: graffiti.
