Have you called a tree company and asked them to dump a load on your driveway? I scored two loads by simply stopping the car where they were working and asking them to dump the chips at my place.

Norman Compost may have wood chips; i'm told they load them with a center pivot front bucket for free. Try, googling norman ok compost facility. otherwise i'm the same way i ask the tree trimmers to dump at my place.

I had to google 'back to Eden'. Didn't even realize that's what I was attempting to do. I got lucky and scored 8 loads of wood chips. Lots of sweat equity trying to spread it throughout the garden. Between the wheelbarrow and the neighbor's tractor, I'm gaining.
