Many, many years ago, a friend of ours at the Lake (I will not name the lake, but it's in the area) lifted a "headway speed only" sign from the channel, and took it to his hometown in Mass. south of Boston, and put it up at the entrance to a railroad bridge, on a major ROADWAY. We all had many a good HOOT when all the little old ladies would jam on their brakes and go about 10 miles an hour til they were under the tracks...........
Oh..........for the good ole days....
