It was my Mexican coke. I did it by accident. Ernie and I were snapping photographs from his car window, he was driving and I was tasked with taking photos. I finished my coke to hold the camera and then put the bottle in the pocket of the passenger door. We drove around for an hour or so, and then got out and parked (which I paid for) and I forgot to get the bottle.
@wglane also, vital info: my car including where it was left, is full of empty water bottles and basically looks like a recycling center.
