You couldn't sell your old house - but you really couldn't sell your old Explorer. Suddenly, in fact, you felt a little less confident that you were an Explorer, a Navigator, a Forester, a Mountaineer, a Scout, a Tracker, a Trooper, a Wrangler, a Pathfinder, a Trailblazer. You all of a sudden were in Kansas or maybe in New Rochelle - not Durango, or Tahoe, or Denali, or the Yukon. Discovery and Escape and excursion suddenly seemed less important than the buzz-killing fact that it took a hundred bucks to fill the tank.
