One can snap an excellent photo of the Batman Building from the vicinity of the Tennessee Titans LP Field.

Nashtrash Tours offers 90-minute bus tours through downtown Nashville hosted by the Jugg Sisters and billed as "a one-of-a-kind country musical-comedy extravaganza." [This is an adults-only comedy show, so kids under age 15 are not allowed.]
The Grand Old Opry is performing at the downtown Ryman Auditorium throughout November.
The Vanderbilt University Commodores Football Team hosts the University of Kentucky on 16 November and Wake Forest on 30 November.
The Tennessee Titans NFL team hosts the Jacksonville Jaguars on 10 November and the Indianapolis Colts on 14 November. One can walk on bridges across the Cumberland River from downtown directly to the Stadium. Or, if one chooses one may arrive at the game
