During warm season, county will chip any wood (except blackberry and poison oak) I drag up to the road side. I have two acres spread down from the road. Not sure if the dragging back and forth is worth it. I'm in my early 60's and don't have a lot of time. But for composting, seems appropriate to get a shredder for cardboard, and newspaper. What are the best shredders available in the U.S.? Seems I read something about lawn mowers being good shredders.
