Remember those — busy signals? Ah, the good old days when you could exhaust your obligation to make an unpleasant call by getting a busy signal. “I tried calling you back but your line was busy.”

Anyway, I won’t be around much for the next couple of days because my dear wife is ill and we’ll be dealing with doctors. I have a couple of posts queued up, and Rod is kind enough to approve comments for me, but I won’t be able to participate in the conversation for a little while.
