Please join us on Thursday June 10, 2021 for a glimpse at history with Sid Langsam’s own movie “Operation: Speed”. This great movie takes a look at all the action at the Continental Divide Raceways here in Castle Rock back in the 1960’s. CDR was a well-known race track for racers of all types. Sid Langsam was the owner of CDR and made a short film about the race track. The presentation will also feature a discussion by local author, Jim Hansmann about CDR and his 2020 book “Racing at Altitude”. We encourage everyone to come and share their stories of CDR also. Refreshments will be served at 6:45pm with the presentation beginning at 7:00pm at the Philip S. Miller Library 100 S. Wilcox St. Castle Rock, CO 80104.
