There’s a tradition in Chicago to dye the river GREEN for St. Patrick’s Day. But as of Friday, the city was saying there were no plans to dye it this year, to avoid crowds coming to watch. Well . . . it turns out that was a bluff. They DID dye the river green after all on Saturday . . . they just didn’t tell anybody in advance, to keep crowds from gathering to watch. It’s surprisingly easy to dye the river . . . it only took about 20 minutes on Saturday morning for boats from the Chicago Plumber’s Union to get it done. But St. Patrick’s Day is still going to look different in the city in other ways because of the pandemic . . . all of the normal parades have been canceled, and there are still serious restrictions on the bars.
