A countywide, weekend-long celebration running September 26–28, 2025. Over three days, residents and visitors can enjoy everything from birthday cake on the Courthouse steps and Happy Hours at local favorites, to a rolling downhill derby in Media and the first-ever Delco 10 Miler. It’s a celebration of community pride and a preview of the historic excitement building toward America’s 250th birthday on July 4, 2026.
