I went to the local Home Depot today to buy a few bags of sand for ballast, as I am having my plow installed Friday. For those of you who are using sand as Ballast,are you buying the 50LB bags of sand in plastic or the 80LB bags in heavy duty paper. The 50LB bags are play sand and the larger bags are a more course sand. The problem we have here in MD, is alot of the time we have rain mixed in with the snow. How do the bags of sand in heavy paper hold up? Any other suggestions that might be better than sand for ballast would be helpful.
