There is a rural stretch of country road in northern Wisconsin that went from 55mph to 35mph for a short while then right on back to 55. A friend of mine, who grew up in that area, said that a boy was struck by a vehicle there and died. Afterwards, they chabged the speed in that section to prevent another acciedent.
The road is now back to 55mph throughout. But for a time, there was a slow parade in unkowing memory that ripple through time and evebtually dissapated into a story.
