Took a time out and turned on the NGO show, titled "Life Below Zero". One of the people on the show was running an old LT 40 woodmizer. Pretty cool to see a mill on TV, exceptional to see one similar to your own.
The gentleman who was milling there said he liked to mill because he enjoyed gathering up the logs, and the feel of making his own lumber. Saving trips to town, and saving money. Sounds like most of us. You do it because you like it, not because you need the exercise!
Not sure if I've got the balls to make it in Alaska, but there's plenty of work here where I live for sure....
