KANSAS CITY, MO—Clad in a pair of revealing, skintight swim trunks, local man Paul Withers strode past an array of plastic lounge chairs Wednesday as though the Choteau Community Pool was a remote, sun-dappled Sardinian cove, onlookers reported. Withers, who seemingly confused the facility’s concrete walkway with a winding path down a rocky slope leading to the gleaming white sands and azure waters of the Costa Verde, then proceeded to mill around the swimming area in full view of patrons, having apparently mistaken the roughly 30 west Missourians for a group of lithe, olive-skinned European models.
