Couple of years ago, I was walking along a road, which is in quietish, non-descript suburb of Bristol (if Pred's watching - the road between the Salutation and Blaise Inn). From nowhere, a couple of police bikes suddenly appeared and blocked traffic from coming out of a T junction.
A minute later, two cars appeared. One of them was a black Range Rover, and as I stared at them to see what all the fuss was about, I could see Princess Anne driving it. They swiftly went on their way, followed by the police bikes.
Just seemed a bit surreal. There I was, walking along, minding my own business - bit of action - royalty drives past totally unexpected - then seconds later I'm back in my ordinary, humdrum day.
