Nowadays when you enter most ballparks, one of the first things you see is a huge Budweiser sign. It wasn't always that way. Each city had their own local beers at the ballpark. In New York The Brooklyn Dodgers Had Schaefer, the Yankees Ballantine, The New York Giants had Knickebocker, and the Mets had Rheingold. What were some of the local beers at other ballparks? I am especially interested in the old ballparks.
