I found a FREE truck load of apple wood on marketplace today. Stacked level 8 ft pickup box. He has a dead hybrid poplar we can cut for firewood. I might take him up on it for some shoulder season wood. It's drive-up wood, since it will land on his gravel driveway, and it's only about 10 miles away.
That hybrid poplar is in the same category as willow. I would not want it. Stinks too, but being dead it might not stink too bad.
