And thanks to the city workers

The success of people-intensive events depends on the hard work of so many behind the scenes workers. This city of Sydney worker was picking up rubish in Hyde Park to keep the area clean for the Catholic World Youth Day revellers.

Today is, apparently Ratcatchers' Day. I hope this young woman doesn't have to deal with any rats!

It's also Pi approximation day in countries that use DD/MM/YY format for dates: 22/7
