All it takes is a stumble and one of you can be out of action. When I suddenly found myself sitting on my ankle on a well maintained National Park pathway no one would have been more surprised than me. But a broken ankle meant that poor Woody had a three thousand kilometre drive with no assistance except for a whingeing navigator with her leg propped on a cushion.
Now imagine if that had been Woody with the broken ankle and if I wasn’t able to tow the caravan. We really would have been up that proverbial creek.
Someone once remarked with surprise when they saw a girlfriend of mine reversing her caravan. She countered with “It’s a damn sight easier than the horse float was!”
