Tree crews have been doing a bunch of cutting along the power line rights - of - way all spring. They chip what they can and leave the rest, all limbed and cut up anywhere from 1' - 10' ft. long. Mostly bigger limbs, a lot of fir and spruce, but if you pay attention, and look around, there's a lot of good stuff. Birch (white & yellow), maple, oak (red & white), cherry......
. . . I suspect most folks will not mind you taking the wood . . . and you no doubt know the area and who will mind or not mind you grabbing the wood.
