Walmart doesn’t make the decision on overnight. The city does. You take your chances on the city asking you to move.

Update

Stopped there today. Spoke to a gentleman who had stayed there in a trailer the last two nights. He Told me that the signage is not enforced. Also told me that half a dozen units parked overnight next door at sams club but the trains are noisy.

No Overnight Parking

Signs are posted.

Safe and clean great shopping...
