To break the tedium of the ride...
It was a tedious bus trip back to Cairo with an interesting stop at a Coptic monastery (of which more later). The part of the drive we missed in the dark wasn't worth seeing - mostly an industrial area. There is a lot of empty desert land which has walls, a gatehouse and a sign for development but no houses have been built. Mahmoud says most of this projected development is Saudi speculators.
The trip was made a bit more exciting by this accident. In the US the road would have been closed for hours and hours. In Egypt, two and even three lanes of traffic simply swerved off the side of the road around the site of the accident and continued on its way.
