Major League Baseball typically avoids scheduling home games for the Cubs and White Sox on the same day. But on rare occasions (it happened five times in 2021), you can visit both Chicago ballparks in succession, with a day game on the North Side followed by a nightcap on the South Side. We’re one of four markets — along with New York, Los Angeles, and the Bay Area — with two clubs, but good luck trying this in those cities. In California, you’ll be sitting in traffic longer than the game itself, and in New York, you have to pass through three boroughs and the indignity of a subway transfer to get from Citi Field to Yankee Stadium. Here it’s a mere half hour on the Red Line from one park to another — there are Wrigley renditions of “Take Me Out to the Ball Game” that have lasted longer. Die-hards may object: Why would Sox fans willingly spend an afternoon with drunk Wrigley bleacher bros? What Cub fans would deign to watch a game at a stadium called Guaranteed Rate Field? Baseball, though, isn’t just our national pastime — it’s our city’s, too. And whether you loathe the Cubs, the Sox, or baseball (and by extension life) itself, on a beautiful summer’s day in Chicago, there’s nothing better than catching a ball game. Or two.
