There were a lot of Racers from the 60s-70s that stayed working at Polaris, Monsruds, Eastman, Bernat, Przekwas, Hedlunds, Knochenmus. For the later Generation you have to remember Polaris discontinued factory racing when Jerry Bunke died, when they went with supporting independent racers, they were against anyone working at Polaris to go racing to keep from upsetting the independent racers. Most independent racers were mostly farmers that had the time in the winter to test and race, when they quit they went back to farming.
