Sams Club parking

I don't make a habit out of overnighting at Walmarts or Sams or others that may allow it. I did Walmart once and did not feel comfortable with it. It was a 24 hour location and some of the cars and people I saw were a little suspect, and this was in a small town in GA, some place you would think was on the safer side. Drugs and the people who use them are everywhere I guess because I watched a couple small time drug deals happen in that lot.
