Tks Stewart,
this road (N85) I know because of going there 5 times with my glider-trailer to Airport/Aerodrome Vaumeilh nereby Sisteron.
B.t.w. the area French Alps I know from flying with my glider from the bird´s eye view.
But thank you very much, it´s really a great road to go.
Greetings from the South of Germany
