I have been to four: three different stadiums hosting the Birmingham Barons, and the Memphis Redbirds current home.
My favorite, and the oldest in America, is Rickwood Field in Birmingham. Built in 1910, over 100 hall of famers have played there! Wagner, Cobb, Ruth, Robinson, Aaron, Mays and on and on. The list is staggering (
