And then there was one

It was only a matter of time, unfortunately, but recently two of my valve stem caps were stolen--both from the rear. This wasn't the first time, either. Let's see, over two years ago I started with four .:R-line valve stem caps from the .:R accessories kit. Roughly one year later I was down to two, joined by two VW valve stem caps I purchased at a local dealership. Now I'm down to one .:R-line cap remaining. At first I thought the thief had taken both of them, but no, he/she took one .:R-line and one VW cap. Oh well. I guess I'll see how long they last this time. :o(
