Here in western Iowa at our landfill the trucks always stopped at the same spot on the driveway. Well the slarf would run out of the truck (like liquid) and on to the driveway. The driveway is made with 2 inch limestone and the deer have dug a hole about a foot deep right in the middle of the driveway eating the soil. Must be something they need in that stuff or why bother. By the way this spot is about 10 yards from the building where you check in to dump. The guy who runs it is a deer hunter and he said he could have shot alot of deer out of there but he didn't think it was morale. I agree with him. You should look at the moralitity of this and ask yerself the same ?
