Really lovely thread. Thanks for the effort.
Over the years, I have managed to work out most of the various twists and turns. I am working on the various signs displayed about the verges being Acotement Non Stabilise, Acotement Mobile etc, current favourite is the often related Boux. I sure someone can and hopefully will correct spelling and lack of accents.
I hardly ever travel in France in July/August these days, but are the booths for the Bison Fute still manned then? I haven't seen a happy smiling student doing their works experience in one in a while, handing out free maps and occasionally bottles of water. They all loved the chance to speak English.
Even without the maps, following a Bis route is both very rewarding, very simple - usually no effort at all.
