Cobblestone Street, Charleston, South Carolina, USA
Every day many people around the world walk through cities and towns on modern concrete sidewalks. In olden days folks often walked with the horse and mule traffic on dirt and rock roads. The cobblestone road was invented to give horses a good grip during all weather. Eventually, pedestrians needed to get out of the way of horses, so sidewalks were invented. Sidewalks can be made of stone, wood, concrete, brick, and any number of smooth surfaces which make walking easier.
