Drive-in theater awaits digital assist

In the summer of 2011 I got to know one of the greatest little drive-ins in the world, 160 miles southwest of Chicago: the Galva Autovue. Nothing elaborate. Just two outdoor screens planted where a cornfield used to be, surrounded by cornfields. But on a warm and starry night, with a couple of hundred patrons in their cars and dozens of kids running back and forth to the concession hut, “Captain America: The First Avenger” never looked better.
