Firewood is simple here. The only special machine used is a beat up old truck, because you don't throw wood in your nice truck. Equipment to get it out of the forest? A 100' cable to drag it out (because longer isn't allowed). Chainsaw? For sure. Waiting for it to dry? Nature does that. You don't cut the green trees, you cut the dead ones.
I wish people around me didn't burn wood, but since they will do it anyways I'm always pointing people to areas near me where there are dead trees standing. I'd rather have them pull it out than wait for a forest fire to clean it up.
It is impressive how fast one guy and a saw can fill his truck and be gone.
