@roger,
Walmart scares me, but no longer so much at the hours I visit.
First time I went there a while ago, I thought I'd be run over by large carts, and I am not kidding. I'm not fast or steady on my feet, but also, not that bad. But maniacs with carts were near running from the doors.
Later, I met a woman in one aisle trying to get up using her cart after looking at the bottom shelf. That was in a quiet time.
I park a long way away on purpose.
I've designed parking lots. This place is volatile.
Of course, walking with your cart is problematic with lined up darters too.
OK, you said the website.
