Guess what happened next.
If you said the sun set, it got dark and very cold, you'd be half right. The other (more scary) half is that we got in the car and then the starter motor threw, what we in Australia might call, a 'spazz' and refused to turn off. Tim tried to jack up the car so he could get underneath the engine to fix the problem. But the sand wasn't stable enough to keep the jack still. So I scrabbled around in the half-dark looking for something suitable; thank god for flotsam and jetsam, I say. I found a big plank of wood to do the job. Meanwhile the starter motor is still emitting its eerie high-pitched whine and the tide is coming in!! Tim gets the car jacked up, lays down on some very mushy wet sand and bangs the starter motor using a strategically placed tyre iron. The starter motor stops. I'd say the silence was beautiful - until we realised the episode had drained the car battery. One turn of the key revealed all. Luckily, because Tim is used to driving a 20-year-old car, he ALWAYS carries a battery recharger, so after plugging it in and keeping our fingers, toes and eyes crossed, the motor turned over and we were able to go on our merry way. And the lesson learnt? NEVER DRIVE ON THE BEACH - no matter how attractive the sunset.
