Sam imitated the gesture as exactly as he could, waving back at the man and assuming it meant that he was alert and all was well. He pretended not to be studying the man for his response, just walked a bit closer to the front of the truck and waited. If he was going to have an automatic-weapons fight, he was going to use the truck’s engine as a shield. He took a few breaths and prepared himself. The other guard turned and walked off along the perimeter.

Sam moved back to where Remi waited. They stayed low as they climbed over the gate of the truck to its bed, lifted the rear canvas cover enough to let them crawl under, then pulled it back down to hide. Once under the tarp, they moved some of the marijuana packages to build a cushioning layer beneath them.

Soon they heard footsteps and voices coming to where their truck was parked. Then Sam and Remi felt the truck sink on its springs a little as a man stood on the left step and sat in the driver’s seat, then another came from the right side and sat beside him. The doors of the cab slammed, the engine started, they began to move, and very slowly the truck joined a line of trucks on the gravel road.

Sam listened to the engines for a couple of minutes, then put his head near the canvas. He whispered, “It looks as though five leave at once.” The truck moved up about five lengths and then stopped again.

This time, Remi moved her head close to the bottom of the canvas on the left side. “We’re sitting beside a sign,” she said.

“Can you read it?”

“Estancia Guerrero.”

There was a sudden surge of movement around the truck, on all sides at once. Sam gripped the rifle, and Remi drew her pistol, and they faced away from each other. Men were climbing aboard, sitting on all sides of the canvas behind which Sam and Remi hid. The men laughed and talked, while Sam and Remi, only inches away, held their fire.

The driver shifted into first gear, and the truck moved ahead, gaining rpms, until it was time to shift into second. But, then, they could tell that other trucks were moving too. And by third gear, the workers on both sides had made themselves comfortable, with their legs through the wooden side gates and their backs leaning against the canvas-covered bales of marijuana.
