A week earlier, whilst walking along the long bricked passageway that runs underneath this famous Parisian boulevard, I’d seen a group descending the observation shaft accessed by the same manhole that I was now stood on top of.  Tonight however, that plaque, tellingly surrounded by muddy footprints and carbide deposits, was unequivocally welded shut.

A statistical analysis of an experimental hitchhiking trip from Paris to Sofia, passing through Germany, Poland, Czech Republic, Slovakia, Hungary, Romania and Bulgaria.  For some reason, the Bucharest, Cluj, Sibiu, Bucharest to Sofia section couldn't be calculated.  Big thanks to everyone who made this possible :)
