BAHAHAHA what do you think nashville is? It isn't dangerous at all there are just a bunch of hobos and they are usually really nice...
You must not seen the areas I have been to. Your right there are a bunch of homeless ppl there, but when you walk down 2nd avenue, or just going through Dickerson road into downtown Nashville, even some of the Eastern parts of Nashville Inglewood, Antioch. Most people don't think that these area are dangerous, but when you get robbed several times in daylight w/ a sawed off shotgun pointing at the tip of your nose then yes, I'd have to say it's a very dangerous place. I can say that because I have been in those shoes. My neighbors house was broken into during the day. They were nearly beat to death over $20.00 which is just stupid.
Not pointing this towards you, but ppl in general are ignorant.
I think Tennessee has most of these ppl unfortunately...
