When this stadium was first occupied in 1953, its capacity was under 29,000, which was increased to over 43,000 by 1954. After two World Series appearances, the tenant left, and the park sat empty except for a half dozen or so football games a year. In 1968, the stadium got new life when a nearby AL team used it for a handful of games over two years, and in 1970, a team piloted its way to this stadium to permanently relocate. Identify this stadium that had a creepy guy named Bernie living in a shack occasionally slide down a slide from said shack, and which, on 20 July 1976 saw Hank Aaron's final home run sail over its wall.
