I use to live in Main South on Stoneland Rd and walk to Clark all the time when I was a teenager, even at midnight. We use to use one of their buildings for dance practices and sometimes collaborate with the dance team they had at Clark. Nothing ever happened to me. I think people tend to overreact about main south. As long as you mind your own business, no one should bother you. That being said, you should still have caution wherever you go whether your in Main South or in the middle of Tokyo.
