We arrive in La Paz in the early evening to be met by that potent symbol of civilization, Burger King. After so many days on the road, it feels odd to be back in a jostling metropolis, fighting through traffic jams and dodgingpedestrians. An early evening beer offers the chance for reflection. There is no denying the Panamerican 20,000 is a PR stunt designed to generate exposure for a brand that doesn't advertise.
But it should be equally clear that cynical ambitions do not necessarily invalidate the challenge. After a rest day tomorrow, the cars roll on to Peru and I wish I were going with them. The past few days have been fascinating. I've driven a Ferrari 1000 miles across some of the world's highest and most dangerous roads, crossing terrain and seeing sights that don't feature in the guidebooks. Goldoni was right, this really was a crazy thing to do.
