>> Walnut veneers ... doing selective harvesting per order.
Wow! Designer trees. I guess that would put a premium value on your product.
"Hilly" does make it sound like a challenge to harvest. I saw one TV show that talked about selective harvesting in difficult and fragile forest terrain, using helicopters to extract single trees.
If those books were accurate, the helicopter would have burned enough fuel to use up five years of profit before hooking the first tree.
Maybe something with dual-use ... ski slopes ...
