Yuletide rec

I haven't been reading much from Yuletide--just a few here and there--and I had no plans to rec anything, but read this one. It is based on Oregon Trail (yes, the game). If you spent hours and hours and HOURS of your life playing it in elementary school, as I did, you will get most or all of the references. It has the most awesome twist ever at the end, and that's why you should read it. No, really. Even if you've never read fanfic before in your life. Go. Now.
