[justmmy.livejournal.com]

Title: Fall Into the Sky
Rating: R for the occasional F-bomb, I guess. 
Genre/pairing: Gen (but if you squint really hard and turn your head, you might see the 'cest hiding in there)
Characters:  Sam, Dean, OMCs
Word count: 9,346
Spoilers: Takes place after the S4 finale, but goes AU after that.
Warnings: Uninspired dialogue.
Disclaimer: .....really? this is necessary?
Summary: Written for twirlycurls 's h/c challenge prompt: Post-apocalyptic world filled with dangers but nothing the Winchesters couldn't handle – except that as soon as they find a relatively safe, secure place to settle, Sam develops severe agoraphobia and doesn't want to leave their house.

Let it not be said that the Winchesters aren't a hardy breed... (part one).
