We planned a guided tour of London for Monday, which turned out to be a beautiful public holiday for Londoners. Some kind of Marathon race in Central London meant that all bus tours were cancelled, and we went to the British Museum instead (which was brilliant I agree with you Jan!). I posted about that previously causing heartburn for my follower, Rod Leflea who passionately believes they are all thieves! On the next days bus/walking tour it rained and rained.
The changing of the Guard got cancelled. While the Guard, who are all active serving soldiers, just taking turns at the ceremonial stuff, can fight and march in the rain the band cannot – their instruments get damaged by the wet.
Fortunately the Horse Guards, and their mounts are made of sterner stuff and paraded from St James to Buckingham Pale right past us.
The coachman need to exercise the horses used for the ceremonial parades regardless, as well.
