"Motorcycle racer Andrea Coleman and her journalist husband, Barry Coleman, couldn't forget what they saw during a trip to Somalia in 1986: hemorrhaging patients being carted to clinics in wheelbarrows, rusting vehicles abandoned by the side of the road, community health workers making their rounds by foot. What all this signaled to the Colemans was a delivery system in deep disarray. It wasn't simply the medical supplies that were lacking -- vaccines, for example, or bed nets -- but more mundane basics such as oil filters and lug nuts, along with the mechanics and maintenance protocols required to ensure transport that was fully functional."
