notice the plank road, necessary to get the heavy truck with the skinny damn tires out of the woods. It's been a while since I posted about plank roads, but what little I learned about them never mentioned them used for logging, and I bet it's due to the ignorance of the logging world by the rest of the driving world that was interested in getting across the sand dunes
