One of the nicest, cleanest Walmarts I have been in. Had a specific spot set aside in the parking lot for semis, and another one for overnight parking. On staff security all night so I felt pretty secure, and enjoyed the beautiful songs of a few thousand Great-tailed grackles roosting in the parking lot trees. The only dropped star is that someone with an *exceptionally* loud vehicle ripped through the parking lot right at midnight, fairly intentionally, but other than that, traffic noise wasn't very bad.

Large parking lot in front of Sam's club/Walmart. Near highway not super quiet but works.
