I have been to Memphis twice on vacation. I love Beale Street. There are a lot of black people. My wife and I hung out on Beale Street with our bull terrier one night. It had to be at least 15 black people to every white person. And I am talking thousands of people. It was comfortable, though. People were there to have a good time.
The culture difference around dogs was interesting because I saw a lot of people were scared/distrusting of my dog. I am sure a lot of it is because my dog was a bully breed. A few people that I talked to asked about her and when I said "She is real friendly. She always likes a pet or a scratch behind her ears." they were still very hesitant, like they expected her to bite them for no reason. I think a lot of dogs down there are used for property protection.
