Boog mentions the fact that sawyers often won't buy fencerow trees, and Ed says it is valuable for firewood.  However, we have so many down trees in this area that can be used for firewood, most of the firewood people I know won't cut a growing tree, they often have a conservation ideal that a tree is only for firewood when on the ground.

Hires is the closest sawmill I know, don't know if St. Marie is still sawing or not.  It would seem that would be where you might get an answer.

Back when Bailey Sawmill was operating, I stopped to ask about tree value.  I worked on weekends during winter in my bottomland, cutting the trees near the farmland, they needed to be cut to keep them from scratching the equipment anyway.  Bailey sawmill said the trees were valuable, and I could make some good money if I would only load and bring them in.  I worked up the logs, loaded them on wagon beds, as I didn't have a truck to haul them at that time, and tractored them in the 25 miles to Bailey.  When I got there, they had stopped buying logs, I took them home and unloaded them in the cow lot.  I inquired several places, nobody wanted to buy them.  I ended up cutting them up for firewood.

We have sold timber out of our woods to loggers, they love a good white oak.  Usually don't get much for them.

Back when we had a sawmill a quarter mile from our house, we cut a lot of our own oaks for fence lumber, the most valuable use is when you have a need of your own, and can get someone to saw them.

I know where you can get a good 7700 Ford tractor to use in the fencerow, Kurt!
