Found it!

Take "wallet" OFF the List of Important Things Rebecca Has Lost in the Last Week (or whatever I called this list in my last post).

Right after I hit "publish post," I remembered that I'd been riffling through my purse yesterday on the way home from work. Sure enough, my wallet was squished between the driver's seat and the seat belt buckle.

Now think good "key finding" thoughts. Who knows where I might have put those.
