NaNoWriMo

I signed up for National Novel Writing Month today. If you don't know what that is, go here. (From here on, I'll assume you know why I'm suddenly pulling my hair out in anticipation.)
Now, I'm not expecting to win, since this is my first attempt, and I have school to go to, but I'm going to try and get as far as I can. I've always liked the idea of NaNoWriMo- trying to put together a book in 30 days means, for one thing, NOT EDITING what you write. I expect that this part will be the most difficult for me: whenever I get an idea for a story, I try to start it, but I always get so caught up in making it perfect that I never get past the first few pages, until I don't like the idea anymore and give up. But not this time! I've been sitting on an idea for a while now, and I think I can roll with it all the way to 50,000 words. The basic premise is your run-of-the-mill, post-apocalyptic, a-virus-has-turned-everyone-into-(insert zombies/insane cannibals/creepy lepers here) story, except the main character has taken up refuge in a high school, using all of the supplies there available to her (think JROTC practice weapons, stale frozen pizzas, science project hand-powered generators.) Her companions may or may not be hallucinations. I'm hoping to answer some of the questions I've always wondered about post-apocalyptic stories: for instance, what happens to people who had braces? Assuming you don't want to take them off with your dad's pliers, would you walk around for the rest of your life with correctional orthodonture?
Anyway, I'm really excited for this. Even if I don't finish by November 30th, I think it will be a good exercise. Anyone want to join me?
