A haunted clown-themed
motel in the Nevada desert next to a graveyard.
What could possibly go wrong?
(I'd be tempted just to play this one straight. Simple player paranoia and genre savvy metagaming would be enough to create all the atmosphere and fill up game time once you describe the place where their car coincidentally broke down. Just sit back and watch the fun. And if anyone complains that the setting is ridiculous, just show 'em the video.)
