PLEASE NOTE: I have seen folks use steel wool as a scatter carrier for foliage. Please don't do this. It is used by the army as a primer for a detonator, and, especially if you use DCC, you run the risk of your layout going up in smoke which happened to a friend of mine. Just try putting a piece of steel wool across a battery!
