Bill and Lyn bought a 24-hour ticket for double-decker bus tours of London, and for the first couple of days they rode around rainy London in damp style.  As long as you kept your feet up, all that water sloshing around the floor of the bus wasn't too annoying.

Here we are approaching Tower Bridge

There's Big Ben and the Houses of Parliament

And Big Ben again

And Tower Bridge again

The Thames

Lyn's having a jolly good time

St. Paul's Cathedral

And Big Ben again again
