There are two variations to Capital City Stadium; one resembled the Houston Astrodome while the other resembled Pro Player Stadium in Miami.
The baseball stadium version of Capital City Stadium appeared in "Dancin' Homer" and "MoneyBART". The stadium's appearance is similar to that of the Houston Astrodome before the 1988 Astrodome scoreboard removal.
The football stadium version of Capital City Stadium appeared in "Homer and Ned's Hail Mary Pass", when the Super Bowl was taking place (Homer and Ned Flanders created the halftime show of the Super Bowl). The stadium looks almost identical to Pro Player Stadium (which appeared in "Sunday, Cruddy Sunday"), except for "Capital City Stadium" signage around the stadium.
