Two girls were hurt in Arizona over the weekend when the inflatable castle in which they were bouncing was carried away by a sudden gust of wind and deposited on the roof of a neighbor's house. One of the girls is still in the emergency room with serious head injuries, apparently in "serious but stable condition"; the other seems to have escaped with only minor injuries. In the future, please, remember to properly secure your enormous air-filled castle; but remember that wind is not the only danger threatening your bounce house-occupying children: Last year, California's attorney general filed a lawsuit over high levels of lead in bounce-house vinyl.
