In the morning we went for a walk to the local market.
Then we packed up
 and left, and drove the short distance to Berck. The gas had run out so
 we tried to get a refill, finally locating one at Bricomarché. Good 
price too at 22.90 euros. We also got provisions at the supermarket. We 
then found the Aire near the beach. It required 10 euros in coins which 
we didn't have, so we bought lunch at the friterie first.
 After parking 
up we went for a walk. The beach was huge and had a colony of seals. 
We 
walked along the promenade to the other end of town, and back past the 
shops. 
We then chilled for a while in the campervan, before going back 
to see the beach at high tide.
Dinner was tartiflette again.
