The reason that you don't feel safe is that you don't get to know any of the folks down there. Try talking to them. There will be people you just don't like, but you ignore them, and continue to get to know others. I can tell you right now there is quite a few I don't like, but I talk to every single one of them whether or not its just to say hi, and move on, or to check on them because they are human.
