We decide it’s time to embrace Wal-Mart’s liberal overnight parking policies for thrift and expediency of travel. For our first night, the hard part turns out to be finding the Wal-Mart. Our first attempts lands us at a closed store, cruising the abandoned lot in the rainy dark. Plan B is a nearby Target, which research indicates also sometimes allows overnight parking, but this particular store is part of a mall and does not own its parking lot. Our third try, a store 8 miles further down the freeway, is a charm, and we spend a comfortable night on the blacktop.
