Breaching the Perimeter

Clearing the final granite step required steady rhythm, but hauling cargo across the revolving glass threshold demanded friction management. The heavy rubber sweep along the door's bottom frame presented an obstructive barrier against my aluminum pull-tab sled. Locating the narrow clearance beside the brass guide track, I aligned the fluorite payload with the opening. Bracing my rigid boots against the stone landing, I threw my weight into the green wire towline with calibrated torque. The sled crested the rubber flange with a muted scrape and glided cleanly onto the polished marble interior. My geological asset is officially repatriated within the domestic perimeter.
