My senior year of college he came to a qualifier at Santa Maria. He was riding around the perimeter of the track with his son on a yamaha 80. those little ones that weighed a ton. fouled a plug right near me, one of our bunch walked over with a plug wrench and gave it to him. plug was sand 'whiskered'. i took over another and got a greeting i didnt expect: "you are a long ways from Coalinga, aren't you?" I told him I was a senior at Cal Poly and he reminded me that the last time he saw me he was borrowing a spark plug too. That was almost 3 years and I about choked. It really impressed my roommate who had taken the wrench over to him.
My hometown (coalinga calif) had some great riding and this one fairly long hill that was simply known by many in the valley and beyond as "motorcycle hill". we had one not to far from it called "Dodge hill" . the word from the 30's was that the first four wheeled rig up "dodge" was a Dodge made vehicle. The first vehicle up "motorcycle hill" was a two wheeled bike and likely an Indian. One of the best known motorcycle racers from the United States was a man called "Sprouts" Elder. Called Fresno home and frequented motorcycle hill way back. the area was a popular one for the likes of Lee Marvin and crew, and most anyone that wanted to see something north of the Mojave Desert.
Ditto What Mike said......everything I've ever heard about the man has been good, RIP Harvey Mushman
