ah yes, it's fresh wood chips which I am using as mulching for the backyard. It is heated and smoking from the inside naturally. It's sort of good for the tropical trees as it helps keep it warn this winter.
I ran out of space in the backyard and started to creep into the front yard, then slowly into the driveway. Still, it is not enough space. I'm doing lots of banana, guava,cherimoya, mango. I can give you a tour if you're passing by again.
