Took a slightly different route through Germany then I'd normally take because the 'A3' was full of road works. The 'ersatz' route (A61) was also full of road works but we got through easily. Infact the entire journey back was easy and good going.
Sat Nat on smart phone however does not like Dunkerque. It played up on the way there (telling me to U turn on a roundabout) and on the way back i noticed it kept 'dying'. It was fine everywhere else...even just across the border, 20 minutes away, in Adinkerke but not Dunkerque!
