One of our neighbors, Mr. Miller, once explained to me that trailer parks like ours had originally consisted of a few dozen mobile homes arranged in neat rows on the ground. But after the oil crash and the onset of the energy crisis, large cities had been flooded with refugees from surrounding suburban and rural areas, resulting in a massive urban housing shortage. Real estate within walking distance of a big city became far too valuable to waste on a flat plane of mobile homes, so someone had cooked up the brilliant idea of, as Mr. Miller put it, "stacking the sumbitches," to maximize the use of ground space. The idea caught on in a big way, and trailer parks across the country had quickly evolved into "stacks" like this one—strange hybrids of shantytowns, squatter settlements, and refugee camps. They were now scattered around the outskirts of most major cities, each one overflowing with uprooted rednecks like my parents, who—desperate for work, food, electricity, and reliable OASIS access—had fled their dying small towns and had used the last of their gasoline (or their beasts of burden) to haul their families, RVs, and trailer homes to the nearest metropolis.
