Speed Signs.
—Most cities and towns have speed limits lower than that allowed in the open country. Some of them even divide the city into zones and make a different limit for each zone. On the outer edge of these zones and the outer edge of the city are often placed signs of warning such as “Speed Limit, 15 miles per hour.” In one city was facetiously added “Go slow and see our city, go fast and see our jail.” On the backs of these signs, the side seen by the traveler as he leaves, are sometimes painted the words “You’re Welcome—Come Again.” All of which is to give the traveler a good impression and thus advertise the community.
