On January 11, 1949, in an effort to draw a Major League Baseball team to Milwaukee, a site was chosen for the new County Stadium at the Story Stone Quarry. This location was chosen over the Wisconsin State Fairgrounds due to its proximity to downtown. Construction on the stadium would begin in October of the following year, and the Braves would leave Boston to play in the Wisconsin city in 1953.
