For much of today I have walked down minor roads that run parallel to autoroutes. The cars and lorries speeding past, me dawdling along. I remembered Autonauts of the Cosmoroutes, one of my favorite books. It matteroffactly documents Julio Cortazar and Carol Dunlops' trip down down the important autoroute from Paris to Marseilles. The Autoroute du Sud. Carol and Julio treat the whole thing as a grand challenge. An expedition. They stop over, sleeping in their van, at every service station, even if they are only a few kilometers from the last. Treating the motorway and the services as a long thin country that they had come across. Adventurers in a foreign land. Never leaving the motorway the journey took them weeks. They got into all sorts of administrative bother, partly because they were inviting friends to visit, with gourmet meals and partly because they were hippies and it was the early eighties.
