Each year since 1973, on the weekend after Labor Day, engines rumble the very foundation of Sublimity. The Harvest Festival began as a simple tractor pull, and while that event remains a highlight, some of its wheels have gotten considerably bigger and more monstery. And that's not the only thing about the festival that's grown. Now a three-day affair, the schedule bursts at the mid-section with events such as a Fun Run, a parade, a KidZone with bounce houses and rides, and bands and magicians on the Coors Light stage. Yet all the fun and engine flexing is for a good cause. More than 25 community organizations, including the Sublimity Fire Department and Relay for Life, benefit from the festival's proceeds.
