Nearly done with Ch. 3

I worked all the way through Chapter 3 and made notes on the one big revision I need to make. It should just take 1 day of work, but I'm going to lose a few days to a trip out of town, so I don't realistically expect to finish Chapter 3 until next Monday. Maybe if I make progress on a lot of other errands and psyche myself up I can put some energy into it for a couple hours this afternoon, but that's a long shot.
