Lived near Getwell and I-240 in the late 90's... we were broken into 3 times in 6 months... including an incident where I held the scumbag at gunpoint for TEN MINUTES before the cops finally showed up... The cop flat out told me "Next time you are broken into, do us a favor and kill the bastard"... I moved shortly after.
As far as "safe" areas in Memphis, I also vote to stay down in Tunica, the hotels are nice, lots of security, and it isn't far to run into town. Beale isn't bad, but if you are going to be there after dark go in at least a fireteam sized group and BE ARMED. As far as good BBQ goes, there are a bunch of little mom and pop places along RT. 61 that are FANTASTIC!! I forget the name of it, but it looks like a total dump on the outside, just look for all the cars... inside isn't much better looking than the outside, but DAMN!!! I do know it was in MS, not TN
