Chicago River Dyeing Tradition

St. Patrick's Day in Chicago is marked by the tradition of dyeing the Chicago River green, a practice that began over 60 years ago by the local plumbers union. The idea originated from using dye to trace wastewater, and the first dyeing occurred in 1962. The process now involves motorboats and a secret vegetable-based powder. Despite environmental concerns, the tradition remains popular, influencing other US cities to dye their rivers green each March.
