I stop at WM one time to pick up supplies for the night. Security came right over to us as soon as we stop. He told us we would be fine where we were, but told us that if we parked over in this certain area we could put the slides out over the grass with lots of room. Saying the truck don't park in that area and it would be quite. Told him we were just picking up a few things and would be still trying to make some miles down the road before we stopped for the night. It was only 3:00PM Thank him for the information. I do put my slides out and check in with management. Never had any problems and all got a good night sleep.
