Snowboards in Londonderry, Vermont. The "snowboards" were made of wooden planks that were flexible and had water ski foot traps. Very few people picked up snowboarding because the price of the board was considered too high at $38 and were not allowed on many ski hills, but eventually Burton would become the biggest snowboarding company in the business. Burton's early designs for boards with bindings became the dominant features in snowboarding. The first competitions to offer prize money were the National Snurfing Championship, held at Muskegon State Park in Muskegon, Michigan. In 1979, Jake Burton Carpenter came from Vermont to compete with a snowboard of his own design. There were protests about Jake entering with a non-snurfer board. Paul Graves, and others, advocated that Jake be allowed to race. A "modified" "Open" division was created and won by Jake as the sole entrant. That race was considered the first competition for snowboards and is the start of what became competitive snowboarding. Ken Kampenga, John Asmussen and Jim Trim placed first, second and third respectively in the Standard competition with best two combined times of 24.71, 25.02 and 25.41; and Jake Carpenter won prize money as the sole entrant in the "open" division with a time of 26.35. In 1980 the event moved to Pando Winter Sports Park near Grand Rapids, Michigan because of a lack of snow that year at the original venue. In the early 1980s, Aleksey Ostatnigrosh and Alexei Melnikov, two Snurfers from the Soviet Union, patented design changes to the Snurfer to allow jumping by attaching a bungee cord, a single footed binding to the Snurfer tail, and a two-foot binding design for improved control. As snowboarding became more popular in the 1970s and 1980s, pioneers such as Dimitrije Milovich (founder of Winterstick out of Salt Lake City, UT), Jake Burton Carpenter (founder of Burton Snowboards from Londonderry, Vermont), Tom Sims (founder of Sims Snowboards), David Kemper (founder of Kemper Snowboards) and Mike Olson (founder of Gnu Snowboards) came up with new designs for boards and mechanisms that slowly developed into the snowboards and other related equipment. From these developments, modern snowboarding equipment usually consists of a snowboard with specialized bindings and boots. In April 1981, the "King of the Mountain" Snowboard competition was held at Ski Cooper in Colorado. Tom Sims along with an assortment of other snowboarders of the time were present. One entrant showed
