I just declared my NaNo at 50,430. I freely admit that a very large chunk of that is disjointed ideas and descriptions of places and people, and comments on life and general junk that I've been letting off steam with during the last month. Eventually I'll make a large amount of it fit together to slot into the novel. But for now I've hit the total.
Now I have serious editing work to do but not for a couple of weeks at least!
