What on earth are you going on about? Are you scared of poor people or something? I've been there at normal hours and odd hours (I hate going to wal-mart, no matter where it's located, but sometimes you gotta do what you gotta do) and I've never felt unsafe.
Yep, same here since I live right down the street from it. Never ever been afraid of that place. I've been there from 9am to 4am and have never felt or been threatened. Had someone preach to me about having Jesus Christ save me, but hey, we do live in Oklahoma, right?
On the other hand, I tried that WalMart I mentioned earlier (68th/Memorial) on a Friday night about 11 pm. I felt like I was walking an indoor version of the French Quarter the night after Mardi Gras. I expected to see someone passed out in the pharmacy with a syringe stuck in their arm that was wrapped by a tourniquet. I couldn't believe how dirty that place was for only being open a few months.
By the same token, my favorite WalMart in the area (in regards to cleanliness) is the one in Sand Springs. Easy to park at and easy to shop in.
