Doug,
Please reference rule #2 which reads; GO HOME WHEN IT GET'S DARK. Don't go dancing, don't go for an evening stroll, don't go get ice cream. You won't want to be sailing at night, so there will be NO reason for you to be out. Trust me on this one. I lived there. Carry your walet in your front pocket and your camara strap should have a break-away strap on it so they don't pull your head off when they steal it from you. I'm not a guy who is overly cautious, so I walked those streets many nights and saw some pretty vicious battles. Christiansted and Fredricksted have more crime per capita than New York City. The value of human life there is much lower than you are used to.
