Any ideas????

So Im trying to find a way of getting free dirt to make jumps. I dont really have a way of hauling it other than a pick up truck. My question is does anyone have some ideas how I can get some dirt for free? Just thought I would see what anyone could come up with for me to try.
 
throw a sign out front of the area advertising for "clean fill wanted"
lots of us contractors are lookin for a place to dump excess rocks/dirt
