Every year, the Chicago River is dyed green for the St. Patricks Day parade. This time-lapse video taken yesterday may seem like it’s in black-and-white at first, but that’s just the colors of the city. It’s a slight shock when the green starts! The dumping was done by members of the Chicago Journeymen Plumbers Union Local 130. Here’s a view from a little closer to the action.
The area of the greening was restricted somewhat by construction further up the river. The green only lasted for the day, but brightened things up for the parade.
