Two years tops for me. That's two full summers and more than double what most locals do.Actually I would guess that it is a small percentage. The large percentage of hearth.com visitors are silent and read only. The core posters here are wood burning enthusiasts and not necessarily a representation of the average wood burner. In full disclosure we rarely have wood stashed that is over 2 years old. But we also don't have any oak or hickory. However, madrona gets a couple years seasoning here.
