There was nothing wrong with the car, thank G-d, it just needed a new battery. Still a financial hit, but nowhere near as hard as I feared.
I did get to stay home, too, which is always a plus, and did quite a bit on the layout for Lonnie Ezell's novel. Didn't gather my notes for the podcast, but managed also to get some stuff done for my Rabbi (who has drafted me as his and the synagogue's unofficial secretary). Also got two patches sewn to my travel pack (about time, too, since I've had most of those since our Europe trip in 2001!).
Like I said, in the end it turned out it wasn't such a crappy day after all.
