Well we don't see many double-decker buses in our small Cotswold village, particularly red ones. I was sat in my lounge when I spotted 2 buses go by, unusual I thought and rushed outside with my camera. I missed the white one coming back but the red one was just turning round so I was able to snap catch it with a cheerful wave from the driver and conductor..
It turns out that they had just dropped off a wedding party at a nearby hall. What a lovely way to arrive and depart a wedding, especially as the bus was nicely decked out with ribbons and had the words on the front, Congratulations Han and Rich Wedding.
I hope they both bought tickets for a long journey into marriage.
Congratulations on managing to make the decision, get your gear together, and then be in a position to get the photo. Who says you need good planning :)
