feet and beef jerky part 2

I got in my car yesterday after work and to my amazement the stench was gone!  I did see some crumbled up cinnamon rolls plastic in the door jam...another lovely present from the better half, but couldn't find anything decomposing.  I emptied the nasty coffee cups when I got home and this morning it was still odor free.

So what was the mystery smell infecting my car?

I guess we will never know.......that is....untill next time it decides to rear its ugly smelly head.
