Now in Wimereux. Trip from Guignicourt seemed to take much longer than it ought to have done. The N42 towards Boulogne-sur-Mer is hilly twisty and generally not very nice. As usual Wimereux is a pleasant place for a wander when the weather is nice (as opposed to being a bit depressing when it is wet and windy).
Stocked up at Intermarché Hyper on way (off A26 at Gauchy). Open all day.
