This "deaf child" sign has marked this block for the 10 years I've known it and maybe longer. How old is that "child" now? I asked a resident who happened to come out as I was passing.
Turns out, there never was a child, really. The neighbors were frustrated by heavy trucks roaring at high speed up the street from a highway construction site. So one of them who has a deaf niece in Minneapolis who visits sometimes persuaded the city to put up the signs, in hopes that would get the truckers to slow down.
And did it work? I asked. No, not really.
