HOUSTON (AP) — Of all the places that have been turned into shelters for Hurricane Harvey victims — a megachurch, a ballpark, a gas station, a bowling alley, among them — the one with the most comfortable sleeping arrangements surely must be the Gallery Furniture showroom. Owner Jim McIngvale, better known as Mattress Mack, threw open a couple of his stores to anyone in need, offering food, clean bathrooms and, of course, luxury bedding. “If this is what you call a shelter, I might not want to go home,” said 47-year-old India Jackson, who marveled at the silky pillowcases, the $1,000 mattresses and the atrium with its live ocelot and colorful macaws. With more than 17,000 people flooded out of their houses, big-hearted Texans, religious institutions and businesses have turned their places into unlikely shelters, giving soaked, frightened and disconsolate storm refugees — two-legged and four-legged alike — a safe and warm place to sleep. Some of these places have proved a homier alternative to the convention centers that have taken in more than 10,000. At Gallery Furniture in Richmond, just outside Houston, a clown and a face-painter delighted the children on Wednesday.
