The group stood looking down at the stack of flattened cardboard boxes.

"Looks like a forklift load to me," said Ron.

"We'll never get the forklift in here," Bill objected, glancing around. "Not without moving all those pallets again."

"Let's just move them manually," Eli said, stooping down and grabbing an armload. "It won't take that long."

He stood, bracing a stack of cardboard nearly an armspan wide against his torso and took a couple of steps. Realizing that he had to do so in order to see where he was going, he began to tack down the aisle between the pallets, swiveling his load side-to-side.

"Follow me," he called. "We need to get all this out of the way before Darryl brings the next pallet in."

First Bill, then Ron repeated Eli's actions and soon the vast workspace was traversed by three figures, seemingly propelled by corrugated-cardboard sails, zigzagging their way toward the overhead door.
