Well it's almost that season again. Lots of other wheeled devices for children of all ages: from prams to pedal cars; from scooters to skateboards; and bicycles too.
from wikipedia:
Retail skateboards were first marketed in 1958 by Bill and Mark Richard of Dana Point, California. They attached roller skate wheels from the Chicago Roller Skate Company to a plank of wood and sold them in their Val Surf Shops.[1]
Five years later mass produced skateboards were sold nationally. These early models were often made in the shape of a surfboard, with no concavity and were constructed of solid wood, plastic, even metal. The wheels were usually made of a clay composite, or steel and the trucks (axles) were less sturdy and initially of a 'single-action' design compared to today's 'double-action'.
