You're welcome Mark, I enjoyed going out to see this place as I never went when it ran. While I was at Cedar Mills Speedway a few weeks later, I found an old poster for Hammond Raceway & it has a pic of the frontstretch with a dozen Sportsman lined up with guys like Brad Mann, Tim Rodgers, Paul Lewis (I think), to name a few. I think there are also pics from the days it ran on the Maritime Race Room site as well, if I'm not mistaken. I think they were put there by Cal Hatfield who drives with the AOW class & who is related to the guy that used to own that track.
Any relation to Ivan Prosser?
