Of course not, Chicago is in Illinois, and, like Kansas, allows people to carry guns around with them. But, in the sense of being deeply outside my zone of normality, the phrase "Toto, I don’t think we are in Kansas anymore" passed through my mind when I saw the notice in the featured image at the entrance to my hotel.
This reassuring sign reminded me that Chicago is more dangerous than Sao Paolo. But crime in a city is not evenly distributed, so I searched for safe neighbourhoods in Chicago. Once I found that the downtown area called the Loop is safe, I figured that I might as well enjoy the experience of being in the city where Alphonse Capone worked, and where sudden death is not a term in football.
Since Chicago was unseasonably warm, I walked a lot. I walked north of the Chicago river a little past the Magnificent Mile, up to an area called the Near North Side, and southwards down to Chinatown. I took buses and trains in this part of Chicago. All this felt perfectly safe to me.
