Laurel- Welcome to the site.... It is great you posted!.... I never knew Rudy except to know that it was him but your comments about how much this meant to him (and the rest of us) is profound!....
Off the topic, the movie "The World's Fastest Indian" has introduced a lot of people to the "Mecca of Going Fast".... I (in Bert's words), a "fellow loyal subject of the Queen" - from Canada, have been going to Bonneville for so many years that I had actually met, more than once, that legendary character (I mean Bert Munro)....
I do not have any other contact info but, if you and yours are ever able to travel to the USA during Speedweek, do your best to attend, say who you are and you will be helped to find and meet anyone who is there that may be on your "wish-list" of people to see - 'specially the ones who knew Rudy!
