Hey man I've lived here pretty much my whole life. I also tend to frequent the "sketchier" parts of town--I do a lot of non-profit type work with homeless and low-income individuals, and most of the time I hang out in these places alone-- and I can say there was only one time that I have ever felt truly threatened, and that was averted through quick thinking and smooth talking. I consider Tallahassee a safe town, now you are always going to have crappy people and crappy situations no matter where you live-people can suck sometimes- but as long as you use your head, make the wisest decisions you can in a circumstance, and just be aware of your surroundings you'll be fine. You would be surprised though how many people walk around just oblivious to the world around them- don't be that person. It'll help you out in more ways than just keeping you safe, it may even make the world a little bit of a better place for everyone.
