In this case, Opportunity has 8 yards of mulch. A guy is doing tree work in the neighborhood somewhere and is looking for someone to take it off his hands. Since his price is right (free) and since the Missus wants some mulch, I told him to dump it inside the secure perimeter.
But damn, that's going to be a lot of mulch. They say you never get as much mulch as you need; I guess we're going to test that out.
