Amanda’s Dad is bike into dirt biking. Having a little experience, I went out with her brother, dad, and a couple of wimpy Germans. We had a fun time.We were riding with a guy that used to work for Harley Davidson. He worked with their acoustic division. From Wikipedia: ” Harley-Davidson attempted to register as a trademark the distinctive “chug” of a Harley Davidson motorcycle engine. On 1 February 1994, the company filed its application with the following description: “The mark consists of the exhaust sound of applicant’s motorcycles, produced by V-twin, common crankpin motorcycle engines when the goods are in use”. Nine of Harley Davidson’s competitors filed oppositions against the application, arguing that cruiser-style motorcycles of various brands use the same crankpin V-twin engine which produces the same sound. After six years of litigation, with no end in sight, in early 2000, Harley Davidson withdrew their application.” I don’t know how involved with this he was, but he had lots of bikes in his garage!As with most things in Wisconsin, the day ended with me buying some cheese and ze Germans drinking beer.
