Half Done?

I'm over 58,000 words into the story now, and I've hit a bit of a hiccup.  I suppose it's mostly a symptom of the fact that I need to stop building and start concluding.  I've never written such a slow-paced novel before, and while it's a good challenge the process of concluding things is a good deal less obvious when there's not many plot points to resolve.  Anyway, I'm plugging along and reassuring myself when things get sloppy that it's just a first draft, which will be entirely ditched for the inevitable re-write anyway.
