The journey is over! Up the country to the west changing to east, and the same on the return trip - we've been from Inverurie to St Andrews to York to Cambridge and finally back to the hotel near Heathrow, 1,259 miles later according to the rental car's odometer. It felt rather sad to drop it off again after it got us so far, even though the companionship only lasted thirteen days.

Tomorrow, all we have to do is get up and be funnelled on to an aeroplane - and yet, that feels so much more daunting than doing all of the above manually.
