In my graveyard, I generally use one wal-mart 400 watt fogger run through a cat litter pail converted into a chiller. Granted, the back sides of the fence have black plastic stapled to them for wind-breaks, but it puts down a good bit of fog, usually 1 1/2 to 2 inches deep. It generally covers the entire ground, but we have had to make "fog-guides" out of leaves, so that the fog doesn't all roll down the hill. With the guide paths, we can control pretty much how the fog rolls through the cemetery, for the most part.
