It seems I don't often see someone say hickory is their favorite firewood. Why is that, any idea? What does oak have over it? I see shagbark hickory above oak in a BTU chart but don't know about pignut hickory. Which one has bright yellow leaves, I see a lot of those this year, incredibly yellow! But I haven't noticed a shagbark hickory here in a very long time. Actually, makes me wonder what hickory species we have here other than pignut.
