I've been typing away for about two hours now, and I have gotten about a third of the way through the manuscript. Yay! Of course, as I go through my changes, I'm swinging back to "gee, doesn't this stink" and that's not a fun place to be. Just gotta push through, get this done and see what Mark thinks about it, since I don't have enough distance from this thing to assess it anymore.
Onward to the next two-thirds of the MS.
