Give me a summary of the early history of snowboarding

Context:
Modern snowboarding was pioneered by Tom Sims and Jake Burton Carpenter, who both contributed significant innovations and started influential companies. In February 1968, Poppen organized the first snurfing competition at a Michigan ski resort that attracted enthusiasts from all over the country. One of those early pioneers was Tom Sims, a devotee of skateboarding (a sport born in the 1950s when kids attached roller skate wheels to small boards that they steered by shifting their weight). In the 1960s, as an eighth grader in Haddonfield, New Jersey, Sims crafted a snowboard in his school shop class by gluing carpet to the top of a piece of wood and attaching aluminum sheeting to the bottom. He produced commercial snowboards in the mid-70s. Others experimented with board-on-snow configurations at this time, including Welsh skateboard enthusiasts Jon Roberts and Pete Matthews developed their own snowboards to use at their local dry ski slope.<|im_end|>
