Wal-Mart Living: Home Is A Parking Lot
"'Gypsy Shoppers', a sub-culture of RV'ers that Wal-Mart has invited to use empty parking lots overnight in lieu of traditional RV parks. Wal-Mart in turn carries a full range of supplies that RV'ers purchase, and benefit from that business. The rules vary from store to store on how long a camper can park at Wal-Mart. Some stores don't allow parking as malls they are associated with have ordinances prohibiting such activity. Many have a three night limit, and others have no time limit at all. A store in Federal Way, Washington is home to a woman who has lived in the parking lot for two years."
