Was in Nashville a few years ago for a Cowboys - Titans game towards the end of year. Got to spend NYE on Broadway. It was a neat experience. Was crowded and had loooong lines for alcohol. Otherwise was a fun time.
My bro-in-law is a Titans fan and it sounds like I may be heading back out there next year with him to check out the new Nissan Stadium.
Oh, and side note, the AT&T Tower (aka The Batman Building) is one of my favorite skyscrapers. It's fantastic and incredibly unique.
