Most words in a day?

Most words in a day?

Here a few weeks back when I was pounding away on my keyboard working on 'Destiny' I broke my own personal record for most words written in a day. On that day I wrote a little over 4000 words, but most days I'm lucky to get 1000 words in. Typically, even on my worst days I can force out about 500 words, but there are a few scattered days where I cannot even finish a single sentence. Generally, anything that gets forced out is either heavily revised, discarded or completely rewritten, but I'd rather force something out then not right anything at all.

Anyway, I was wondering about the folks hereabout... What's the most you have ever written in a day?
