So I was driving home, along one of my usual routes late at night. I was just west of Santa Rosa on Hall Road, just barely in the country, when I hit something and heard what turned out to be the sound of air gushing out of my right rear tire, then what sounded like metal rolling on the roadway. So of course, I pulled over right away, dragged out my flashlight, and quickly discovered my right rear tire was flat.
I had forgotten my cell phone. But to be honest, it is a bit more than forgetting.
