Let me give you some advice: If you don't already, bring you a fire arm if you are passing through Frazier, Hickory Hill, or Raleigh. Some of the most dangerous areas in the U.S.. Bartlett tends to be very safe, and a lot of our cops are ex-Marines and such so you shouldn't have any trouble there, just they are very strict (unlike the crappier Memphis Police Department).
A few places I would recommend you visit are as following: Nathan Bedford Forrest Monument, Shelby Farms, Civil Rights Museum, Mud Island, Beale Street, and if you like zoos (which I hate and view as torturing to animals), then the Memphis Zoo is well rated
