It is difficult to make a front yard menacing by daylight... but this is the future graveyard for the TOTs to view.  Rather than wrestle with electrical cords, the lighting will be handled by a handful of LED flashlights in light diffusing boxes.  The graves will face the house.  Rather than attempt realism or go solely with puns and abbreviations, I am experimenting from grave-worthy quotes from movies to test the nerd cred of my audience.  The creepier and borderline sacreligious gravestones will go in the walkthrough section... not open to the younger TOTs.  Again... this should look more spooky at night.
