Lumberjacks don't give a spotted owl's hoot about needing a level playing field.
Women compete alongside men and no one laments the fact that women carry their weight lower.
In a race, no one cries about soft wood catching the ax or hard knots slowing the saw. To lumberjacks, that's part of the beauty of real wood trees. Lumberjacks know what to do with a good forest. It's a darned good thing too because I'm sure that if pencils had always been made from stone we'd all have forearms like Popeye the Sailor Man. With a world like that the stress on spinach growers would just be too great.
