I had a guy getting me bags from the local Bridgestone tire plant. They were big pieces of plastic that covered the steel for the tires. It was sealed on both ends and the steel was inside. When you cut the plastic in half it made two large bags that were 6ft. X 6ft. Now on to my question. Where can you find large bags to haul leaves and clippings???? I have bought tarps and sewn them together to make bags but that gets expensive.
