Next we pick out spots in the yard for our "zombies" usually 2 to 3 people will work, weve even done it with one, but the more the better. We clear spots for then to lay.
The other things you can do for atmosphere that we have done is, hung a strobe light above the center of the room set on the lowest setting so it flashes once every couple seconds kinda like lightning, with sounds of thunder and crickets,bugs,crows in the background.
Before your guests come through you bury your actors in the leaves make sure that they arent noticable, in other words make them match the surrounding level of leaves (NO BIG LUMPS)
As your guests enter the room the walk down the path, the leaves make a rustling noise to there left, then there right, and straight ahead....there only option is to move forward, as the do the first hands reach up through the leaves then another set, and another....they move forward faster. The actors start pulling themselves up out of the leaves...they move very slowly toward the guest falling in behind them....pushing then toward the exit.....finnaly they emerge safe from the graveyard....and on into more danger!!! hahahaha
