Working while gardening

I don't normally work on the book on weekends, and I don't plan to today, but I making a stop by my desk this morning to thumb through Ch. 3 and re-acquaint my self with it and its problems, so that they can nag at me while I'm in the yard. I've found that while I'm doing something physical--gardening, walking, working in the weight room--sometimes yields some helpful understanding about the book, so I've gotten better at planning for that, putting the rock in my shoe at the right time.
