As we drove north, from my seat at the front of the coach I could see in the sea loch a fleet of Viking longboats with the most beautiful decorated sails. I called to all the passengers behind me ‘Quick! Vikings! Get your cameras ready!’

I was so concerned that my fellow photographers had the best opportunity for a fabulous picture that I was rather too slow myself in preparing my own shot. By the time I pulled out my own camera the ships were already setting out to sea.

There was further excitement at the port. Here a diver brought an ‘ancient’ bottle up from the seabed. It looked just like an ordinary plastic bottle of lemonade to me, but everyone else was enthralled at suggestions of its potential archaeological significance.
