Whether he's contacted anyone or not, doesn't matter, no one will give him a plug nickel for it. No mill will touch a single or yard tree. Walnut is not worth what most people think it is. We've actually had truck loads of logs between 24 and 36 inches, 12' long, and the mills wouldn't offer beans for them. I have all the free Oak I could ever use so I don't want Walnut for firewood. We would wholesale it out to a guy that sold firewood at a farm market, $50 bucks per load, 12' bed 6' high, just to get rid of it. Some one on the Milling forum might pay a little for it. If he told you you could have it for cleaning up the rest of the mess, he's coming out on the good end of the deal.
Another thing to understand about good saw logs is the timber market is verry up and down. If you have a place to store logs you can do OK. We were a relatively small company, 2 crews, with a 5 acre base. Between chips, good firewod, and equipment , we didn't have space or time for the logs. It was easier to just get gas money and wholesale them out, Joe.
