Using the non toll road takes 1h15 longer and is a bit of a difficult one if you go through Lille. But the toll road is very boring!
Check Google maps. One route even goes into Belgium and their roads are awful!!
I'll see you in Auxerre next Saturday matey. We're gonna take it on the chin and bash down the toll roads. Looks like the weather is set fair for you once again. Looking forward to getting my feet up with a couple of cans of John Smiths before we get down to the serious business of sampling the local brews.
