I took my daughter archery hunting Saturday evening. On the way into the woods, I found several pine knots laying around. The rest of the tree must have rotted away leaving these behind. They were heavy for their size, so I tossed them at the base of a tree by the trail. Picked them up on the way out and split one open at home. Yup, sure enough, the inside is pure fatwood! Probably 1-2 lbs just from those couple knots. I'm heading back this week with a bucket to collect some more.
