Around our place we are fighting mud right now. With gravel anywhere from 11 - 15 dollars a ton I was wondering if anyone has found any cost effective or free sources to help those heavily travelled areas on your homestead in the fight against mud. I have access to a shingle tabs that I can get for free from a local owens corning shingle factory. I am just not sure if there would be any environmental impact to my drinking water from these or if they are innate. Looking forward to hearing of peoples solutions.
