You’ll be safe if you stick to the main roads and avoid the patrol routes that run along the river. Pick a time when traffic is low, say between 2 a.m. and 5 a.m., and drive straight to the service road that branches off the highway near the quarry. That road has no cameras and only a few patrol cars on duty. Keep the cargo in a covered, weather‑proof container—no windows, no obvious signs of weight. Use a GPS that drops the route on a local hard drive instead of transmitting it over the network; a small, battery‑powered recorder will be enough. Finally, if you have to turn onto a secondary road, keep it in the shaded area behind the trees so you’re out of sight. Verify the traffic patterns a day before; if anyone’s on the road, reroute.
