AP's Colin Adams is in the neighborhood outside Olympic Park:

I arrived at Stratford at lunchtime today ready for a long shift. Stratford is buzzing with excitement. I could hear whistles and horns and people shouting — sounded like a great party atmosphere.

On closer inspection, though, I found a crowd of protesters outside Westfield Mall, adjacent to the park. They were the ones blowing the whistles and causing the commotion. They were protesting about the pay and conditions of the cleaners on London's transport systems.

All very good natured and up-beat, but could we be seeing dirty trains during the Olympics?
