Peyresq, Alpes de Haute-Provence, France.
Peyresq is literally at the end of the road. It ends in the village plaza (‘plaza’ is a bit generous; dusty circle is more apt). There are two permanent residents in Peyresq. This is also the minimum number of people required by French custom to be provided with a postal and road cleaning service: every day these two residents have post, it must be brought to them; all winter, the alpine road must be kept snow-free.
I stayed here for a ten day summer school. This is a long time at the edge of civilization, and re-integration into the Nice metropolis was scary (I shirked Monaco). This isolation breeds companionship, making Peyresq a perfect location for interactive summer schools and the like.
