Wrigley Field turned 100 last year, and next year marks the 100th year of the Cubs as it’s tenant. But the Cubs have been around a lot longer than the stadium. The team existed for decades before they relocated to the North Side, decades before they were even called the Cubs! There’s a new book brimming with stories from the earliest days of the sport in The Windy City. It’s called Before The Ivy: The Cubs’ Golden Age in Pre-Wrigley Chicago. Author Laurent Pernot sat down with Morning Shift’s Jason Marck to talk about some of the history.
