I did it! Three minutes to midnight, local time, I hit 50,390 (50,729, according to OpenOffice), despite the last few days thinking I'd miss the deadline by just a few thousand words. I wound up writing almost 5,000 words today, and more than 3,000 yesterday (schoolwork + Thanksgiving Break = a bad week for fun writing), but I did it.
Congratulations to all you other 50Kers, and to those of you not quite there yet, keep going! I have faith in you! <3
