My son Joshua asked me to help him build at composting bin for Earth Day 2012. We decided to build it out of re-claimed lumber that we found in our garage and from old pallets donated to us from our friends at Apex Landscaping. My son has been actively composting everything he can ever since and I don't even have to ask him to mow the lawn anymore. Now he does it for the grass clippings so he can add them to the composting bin.
