Doctors have a certain knack for prescribing antidotes that soothe and relieve — both for patients, as well as themselves. In the fall of 1967, a certain Arkansas pediatrician was suffering from an acute case of automotive blues. A shiny new Airstream trailer was parked in his driveway. He was in need of a big, comfy and powerful tow vehicle to haul the family on cross-country vacations. So the physician sought solace at his local Chevy dealer, McCurry Chevrolet in Heber Springs, Ark. He went in and checked boxes to order a four-wheeled tonic that was sure to lift his spirits.
