This morning, while I was being really cranky and going through stacks of crap that had been collecting dust for months, and rearranging stuff shoved haphazardly onto closet shelves, I pulled down the Eddie Bauer diaper bag that I bought so R. wouldn't have to carry the purple leather handbag I usually use for A. (T. has his backpack still.) As I went through the pockets, lo and behold, there they were. It's a black bag. Both cameras are in black pouches.
Worst of all, I had searched _that particular bag_ TWICE! looking for the cameras. I don't know how I missed it.
ETA: And a few SD cards in the case with the camera. Which are always handy to have around, especially the 2 Gig one.
