I put a green and blue floodlight on one side of my driveway. I really like how lighting from one side looks. It creates definite shadows on the other side of props. I chose cold colored lights because the haunt is swamp themed. I also downloaded some swamp sounds from http://www.freesound.org. I combined different tracks like the croaking of frogs and muddy footsteps in audacity, exported it as an .mp3 and burned it to a Compact Disk (remember that there's a difference between a CD-R and a CD) with iTunes. The reason it needs to be a CD is because I'm going to be playing it through a CD player on loop. I have thought the atmosphere through a little more this year. I suggest you do the same, you'll end up with a much more cohesive looking haunt.
