Huge Grande Arche in La Defense
On my way back to the city center I biked through a huge park. At some point I turned a corner and there were numerous ladies of night, all in various stages of undress - even though it was broad daylight at 4p in the afternoon right on the main road through the park. Then about 100 yards away was the most sedate, manicured gardens. In here a policeman blew his whistle at me and furiously told me no bike riding. Of course I thought 'do you have any idea what is going on just around the corner!'
