So the next day Rufus towed his trailer up New Marble Mine Road and parked it just outside the mine entrance. In the shady space just inside, he set up a camp table and chairs. This area was largely bug-free and comfortable for much of the day, but sunlight bouncing in from the canyon walls made it bright enough to read and work. He got busy upgrading his drones with the transponders that had been supplied to him by Black Hat.
