Excellent. I want to know what happened next for the quarry truck and for the bridge lorry. But the car on the lighthouse island, the Why is easy - to carry all the shopping from the boat to the lighthouse when it's raining. But the How is more difficult (a) there's no space to turn round at the jetty, so half of each journey always has to be done in reverse and (b) there's no petrol pump on the island - I suppose a full tank would last for several months or even years to-and-fro each day - but what then? Push it off the cliff and buy another with a full tank??
