A 14 year-old boy with a history of running away found a place where he could run away to, enjoy almost any food he wanted, a variety of clothing choices, and moderately clean bathrooms. He chose Walmart.
He made a "structure" between displays and made it four days before store security finally caught on. It's kind of impressive to see what elements he put into place.
You can see the pictures and a little more about the set up HERE.
