i would definitely stroll down 2nd broadway downtown and at least look at all the bars where all the live music happens. demonbruen st is a good time for night life. ummm....the museum downtown i think is worth it. centennial park is nice-see the parthenon. if she is in to music, i'd suggest the country music hall of fame....definitely hit the bluebird cafe-amazing music history in that place. i'll think of more....it's really early/late for me right now.
and if she'd like, i can suggest some great local places to eat.
i miss nashville.
