Maybe you should try visiting some new cities where you don't know your way around.
Once I was in Washington DC in a rental car with a co-worker and at a stop light a black guy came up to the window and said "what are you doing? Do you know where you're at? You need to get your ass 2 blocks that way before something happens."
We crossed an imaginary line in a city in which I'd never been and weren't safe because of it.
I could easily get into that in St Louis.
