I've got big gaping holes in my story from last year (wherein I skipped from the middle of the story to a scene I wanted to write later on, and then continued from there, but still didn't get to the end of the story). I skimmed through much of it now taking notes on names etc. so I can muddle through, and I want to pick up again tomorrow.
I'm not gonna be a nano dork and start writing at midnight... Though I could, I suppose.
Oh, and I have to find this year's nano spreadsheet.
