It's really is nice when mother nature provides the resources you need for free. All you have to do is go out and pick it up off the ground as with the firewood! That is awesome and you got to keep that wood furnace going to keep things heated, glad that worked out so nicely. That's why I've always loved gold panning and hunting for gold nuggets with the detector, pick up resources for free just sitting under the ground. It doesn't get much better than that!
