Changes

Go down the ''Avenue Carnot'' along the ''Massy-Palaiseau'' railway towards the ''autoroute''. After a while there you will see a long stretch of a road with lots of space for cars. Keep going and you will reach a roundabout. If you keep following this road, you will reach a motorway exit underneath a bridge. It would be a good idea to use a sign with "Chartres" as this will make sure to get a ride at least to the first ''barrière de péage'' (30+ km) at St.Arnault. When already there, you might as well pull up or to the service station 5KM down the sign "SPAIN" - you might even get a truck straight to Portugalroad.
