Glad to hear you found it. I had once left my keys in my ignition and left it for about an hour. Luckily, one of my students told me about it. Since then I always slap my pocket to make sure my Keyes are there. Whenever I do something out of my parking routine, I tend to forget things -- keys, taking something out from under the seat, or top case.
Strange, how we're creatures of habit.
