After months of meticulous planning, well OK, the detailed plan was to drive off the ferry in Santander next Monday turn right and follow the northern coast then turn left and drive south through Portugal until hitting the sea again, is looking like a bad plan. The problem seems to be a massive low off the coast of Portugal which is dumping rain all over the country and big chunks of western Spain next week. New plan needed. Probably turn left now and follow the Pyrenees down to the Mediterranean. Good job we haven't booked anywhere!
