I was riding along, hearing a slight noise, looking down to see if I could see what was causing the noise. Next thing I knew I was going over the handlebars. I remember thinking as I was going over the bars--"I just got doored." I policed myself up, all set to go off on someone for dooring me. Sheepishly, I noticed that there was no one else on this quiet, residential, street except for myself and this white car.
