Riverfront Stadium, later Cinergy Field, was the home of the Cincinnati Reds (and Bengals) from 1970 until 2002. The Reds captured three World Series titles (1975, 1976, and 1990) while playing there. The Bengals won the AFC Championship there in 1981 in a game known as the Freezer Bowl. They punched their ticket to the Super Bowl there again in 1988, downing the Buffalo Bills.
