A narrow escape

I had been warned. Loading heavy sheets of plywood and lengthy strips of siding and a storm door into the back of my minivan at a lumber yard tent sale, I had been warned not to tie the tailgate of my van open to fit it all inside. “Once you get going, you’ll create a vacuum,” the man who’d sold it to me warned. “It will suck exhaust into your vehicle.” Happy with the deals I’d scored, I paused for only a moment, considering the danger.
