Texas Walmart stores all have pretty big parking lots, loaded with parking spaces. Finding a spot close to the entrance isn't always easy but I doubt anyone has ever NOT found a space at all.
The one thing I can confirm that Lubbock drivers seem to be the worst at is parking. I don’t know why that is, maybe it’s a lack of parallel parking or sheer obliviousness, but there are some horrendous parking jobs I see on a daily basis.
