..ever put it back together and take it out for a test drive, windows down and hear a "tink, tink tink" as you ride down the road. Also notice your rear view mirror shaking a little more than usual. Noticing something shiny darting off into the ditch on the driver side, thinking - were those LUG NUTS.... CRAPPPP!!! I was nineteen, and forgot to tighten some lug nuts...
