“Eventually the river will reach the Atlantic. Then we can hug the coastline down past Portugal, round the Straits of Gibraltar, up the Mediterranean and approach the campsite from the south. Hey! That saves us getting lost in Barcelona! Brilliant”

He was losing his sense of humour, I could tell. I was already dreading the rest of the trip.

“What do you think kids? Anybody in the back know the Portuguese for thirty liters of petrol please?”

He ate some more caffeine tablets, wiped his tired eyes with a wet wipe and sullenly drove on, keeping the river on our left.

More by good luck than good judgement we found the way out of Orleans and rediscovered the auto route south.

Once again we were low on petrol, but we insisted dad keep driving until we reached a Total filling station so we could add to our collection of miniature plastic busts of famous French people that we had never heard of. The lady who took our money handed me a small plastic Voltaire. I showed her our expanding haul of plastic busts to indicate that we already had a Voltaire. She kindly exchanged it for a Debussy and threw in a Jules Verne for good measure. The day wasn’t going so badly after all.

Evening turned to night. In the back of the car we dozed fitfully as dad drove on, ever closer to the Spanish border. By now dad had been driving for over twenty-four hours, much of it on the opposite side of the road to what he was used to. It was a stressful journey, particularly for dad.

Despite having consumed the caffeine equivalent to a couple of Starbucks Coffee Houses, his head was starting to nod and he was struggling to maintain concentration.

“Its no use love,” he admitted to mum. “I’m going to have to pull over and rest for half an hour.”

Ever since his time in the army he has been able to catnap for half an hour, then wake up refreshed and ready to go. A very useful knack if you have it.

At the next services we picked up some more fuel, thirty liters to be exact, and a plastic Chopin. To one side of the service area was a large car park with a picnic area. We parked up in a quiet corner. Mum woke us all and pulled us from the car so dad could recline his seat and stretch out a little.

We were somewhere in the Massif Central. The elevation made the night air cold, so we pulled on our coats. Tired and irritable, the Quasimodo children followed their mother to a nearby wooden picnic table, where she distributed soft drinks and the last of the sandwiches she had prepared before we left Manchester.

All four of us were fussy eaters. Mother always indulged us by making a pile of sandwiches to cater to our individual tastes. She need not have bothered this time. By now the sandwiches were so stale that they were not so much food, but more like a new form of composite building material. After a few half-hearted bites I left mine on a wall for the birds. Really it was not an act of kindness. Any poor bird that managed to eat some of my leftovers would probably find itself too heavy to take off for a week. We spent a very boring hour sat around the picnic table, before dad at last emerged from his chrysalis like state in the car. Fresh as a daisy, just as predicted.

“Let’s go guys. With a bit of luck we could be on the beach by tea time,” he assured us.

By the time dawn had risen we were within an hour of the Spanish border. Time for another fuel stop. No Total station around this time, so we had to make do with patronising an Elf station and collecting some glassware instead.

We had reached a large service area with an out of town shopping mall. Mother had noted our lack of enthusiasm for last night’s sandwiches and suggested we visit the hypermarket for some fresh supplies.
