Dick Ralsin’s storys of the 1912 race.

Sorry but Dick has taken down his website.

I emailed Dick and asked him about the stories of who the mechanic was in those famous 1912 photos and he told me to keep looking because there were five pit stops in that race and it is possible Pops was in the car at the end. Some very interesting stories by an insider about auto racing. With a good insight into the personalities and characteristics of these men.

Nothing at all to do with Pops except the photos of race cars of the time and he was in 1912 race. If you like old race cars this is interesting.
