in case you haven't seen this, it's an amazing and very comprehensive photo gallery with commentary by a Dane, Jacob Holdt, hitchhiking around USA, some years ago.
Extract from Chapter 1:
Traveling in such a deeply divided society inevitably was a violent experience:
4 times I was attacked by robbers with pistols,
2 times I managed to avoid cuts from men with knives,
2 times frightened police drew guns on me,
1 time I was surrounded by 10-15 blacks in a dark alley and almost killed.
1 time I was ambushed by the Ku Klux Klan,
several times I had bullets flying around me in shootouts,
2 times I was arrested by the FBI, and 4 times by the Secret Service.
I lived with 3 murderers and countless criminals.....
...but I have never met a bad American!
That I survived I owe to my stubborn belief in these words by Jose Marti:You must have faith in the best in people and distrust the worst.
If not, the worst will prevail.
