2009 marks the 50th anniversary of the Ski-doo® snowmobile. Joseph-Armand Bombardier was not the first to develop a snowmobile, but his version was the first to be manufactured in large scale production. The Ski-Doo® has had great success. Conceived as a utility vehicle, the snowmobile later became a sports and recreational vehicle. Because of its growing popularity, regulations and specially designed trails became necessary. Even today, some people complain about the roaring noise of this recreational vehicle.
