The fifth of November is Guy Fawkes Day (see link above photo).
In 1993 Richard, Sara and I were standing on Westminster Bridge in the evening watching the fireworks on the horizon. It was an eerie feeling, standing so close to Big Ben and the Houses of Parliament, and I commented that it would be good night to blow something up (just joking, of course!) Almost immediately several carloads of police arrived and began quietly, but urgently, shepherding people off the bridge, telling them to move well down the street.
The reason? A stationary car on the bridge had its bonnet up and the police suspected there may have been a bomb on board. Only a week earlier the IRA had killed about 30 people in a pub in Northern Ireland.
We didn't hang about to see if the police were right - it was a genuine breakdown, no bomb - but took the train back to our B&B as this was our last night in England after almost 11 months. The next day we flew to Boston, USA, to begin our six-week trip home.
