hello. I have been in Chamonix Mont Blanc and it was loverley. Drove back to geneva airport on an uncrowded 2 lane autoroute yesterday am at 160kmh and it was a pleasure to pay the tolls (5 euros in total). The most pleasurable drive of my life - or high up there. Mont Blanc and it's sister's and brothers lit up by alpinr sun certainly beat anything the M4 has to offer. ***deeply contented sigh***
