TREAD — One of Colorado’s most controversial stories comes to the big screen.
On June 13th, the Winter Park Film Festival is bringing Tread to The Foundry for a special community screening.
Pushed to his breaking point, Granby welder Marvin Heemeyer transformed a bulldozer into an armored machine and carried out one of the most infamous acts in Colorado history. Tread dives deep into the events, the people, and the questions that still divide communities decades later.
This screening goes beyond the film itself. Special guests featured in the documentary—and individuals whose lives were directly impacted by Heemeyer’s actions—will be joining us for the event, offering a rare opportunity to hear firsthand perspectives from those who lived through the events that changed Granby forever.
