My guess is underwatering? Too obvious, I know, but that's all I've got.

Thanks, Christopher! ;) It's never too obvious!
I was going to post these pics to Mike's Thread on watering techniques, but I didn't want to hijack. A few of the leaves were soft (but not yet wrinkled), so I watered yesterday. Lord knows I let my succulents go too dry sometimes....

I'm trying to break myself of the habit.

looks like teeth marks to me.

That's exactly what I thought, too, Randy. Josh, you have something/someone toothing the leaves, IMO.

Looks like possibly a young deer nibbled it...

Thanks, all!
Speaking of eating leaves, have you ever tasted the leaves of Crassula ovata? Let me tell you, they are quite unpalatable.

Anyhow, bad news on this Jade.
I left it out until well after midnight, and the temps were down around 28°F. When I brought it in, the leaves had begun to discolor. So I'm looking at a total frost-chop, now. We'll see how much tissue dies.
