Lots of comments to which to respond, lots of things to post, not enough time

Sorry I'm a bit backed up in responding to your comments. Things are going to be a bit crazy around here for a few days, as our son is coming home from college tonight, doing a quick turnaround include laundry, packing, and trips to doctors, and leaving for Japan next Wednesday for six weeks of study. I'll get back to you when I have a spare minute.
