Setting aside some notable exceptions (Compton, Detroit, East St. Louis) you're not likely to visit anywhere in the US that will pose any significant danger to you beyond what you experience in your home town.
You don't know, IAL is from the North, where ferrets leap from people's trousers and viciously attack at a moments notice, and swarthy groups of flat-capped men lurk around every dark alleyway corner where they compete to regale you with stories of their troubled destitute childhoods and subject you to close harmony singing.
Tis a scary place.
