We wander into the guts of the stadium for another beer or a bathroom break and see where they have hung on the walls images of old teams who played here, including the Athletics, the Alouettes, and the Braves, members of the Provincial League and, later, farmhands for Boston and Milwaukee. Warren Spahn pitched in this very ballpark. Hank Aaron hit a home run here. They modeled this park’s design on Trois-Rivières’ home field, built a year earlier. The Expos installed an affiliate in the ’70s, called les Carnavals, and later, the Metros. Gary Carter and Andre Dawson took their hacks. Though unique, Québecois baseball is nothing new. It goes back decades, or a century, or more.
