I would say free but not really. I have a black walnut tree that needs to come down. It's just under 24 inches in diameter and about 100 feet or so tall. It is straight as an arrow, and has never had anything attached to it, so it's safe to mill. It is too close to my pool and the wife wants it gone (its very messy and the walnuts stain the pool). Anyone who has the expertise to safely remove the tree can have it for free. Or, (preferably) anyone willing to pay for the cost of removing the tree can have it. I'm located in Northern NJ. It pains me to see it cut down, but we really have to.
