As you must have gathered, I have been swamped since I got home from my trip (in part, playing catch up after devoting May to this project). I drafted a post for this site earlier this week. The following day, my computer suddenly began making a very bad-sounding clicking and scraping. It had to be put down at once. Since I hadn't backed up since the middle of May, that post was lost—along with my spreadsheets from the last 3 weeks of the project.
I don't know when I'll get my computer back, but I would expect it to be in the next week or two. Meanwhile, I'm using a borrowed computer to rewrite the talk I'm scheduled to give in just two weeks.
I'm still taking pictures and plan to return to regular posting once this talk is complete and delivered. Thanks for bearing with me while I get everything back in order and in running condition.
