on my mission, was riding my bike in the little space between a guardrail and the actual edge of the bridge over a river. it wasn't a bike path or even a sidewalk, just a narrow space that I thought was big enough to ride my bike through. we were in a hurry and it was too far to go around to another bridge miles away.
my left pedal caught the support poles for the guardrail and I flipped over my bike and the guardrail into the traffic lane. a big delivery truck was in that lane and passed within 12-18" of my head as I laid in the roadway. would've killed me instantly, God looked out for stupid, impulsive missionary on that occasion.
