Two local community groups held charitable functions to help raise funds that would make improvements to the town. One of these charitable functions was the World Pillow Fighting Championships. A steel pole was made to span the Los Guilicos Spring Creek, which was then filled with mud and the Pillow Fights became an annual event. The last World Pillow Fight Championships in Kenwood were held in Plaza Park in 2006, and subsequent events have been held around the United States. A return to Sonoma County is planned for 2019.
