[quote name='pacifickarma']Isn't there a hockey team in Nashville?[/QUOTE]
Yes, but after this week, their season will be over. For that matter, there's an NFL team here too (Tennessee Titans). Not sure if he's just planning on being here for the summer or what, but sports wise, there probably won't be a whole lot going on. The Milwaukee Brewers AAA team plays here, the Nashville Sounds. Only one level below the big leagues, and tickets are usually dirt cheap. Vanderbilt University is also here...and their sports teams have really been improving lately too.
A lot of the other stuff has been covered, but I'll echo that heading down to Broadway and checking out the various bars and honkey tonks is still entertaining even if you're not a fan of country music. There's a lot of good food and even karaoke going on a lot of times. And if you decide you don't like it...there's a Hard Rock Cafe right down the street too.
For those who don't know, there are numerous bars for rock music too. It's not just all country all the time here. 3rd and Lindsley is a pretty cool place, and a lot of big names have played there over the years. Others include Mercy Lounge, Exit/In, The End, Dan McGuinness Pub, The Rutledge, etc. And the great thing is, because it's Nashville, there's live music every single night...at all of these places. Just start Googling and see what you like.
There are several museums if that's your thing and the Nashville Zoo if you like animals. Lots of malls and places to shop. Opry Mills Mall is huge and insane most of the time...and reasonably impressive considering it got hit bad in the flood in 2010, and was closed and potentially going to be torn down for a good while. Nashville is really like most any other good-sized city. Depends on what you're into.
