ok it's not the best route here by a long way but it's so much better than the tedious autoroute and a great start to France. Abbeville town centre is very slow if you go straight through the middle. some lovely twisties and some great very fast straights too.
If you're heading south start waving at your fellow bikers regardless of what they're on, you're not in south east England any more!
wonderful alternative to the autoroute or N roads, excellent surfaces fast, flowing turns many quite safe to overtake around the outside due to excellent visibility.
La Ferte Vidame is well worth stopping at for a break.
