Hi mifho,
also walked the red light district, most of the "ladies" in the window were scary! ;D
Great fun but care needed. Many years ago, a group of us (men with wives!) visited the red light district of Paris. I decided to make a video but hid the camera in a hold all with a hole for the lens. Nothing sinister, just the shops, "ladies" on street corners etc. All was going well until one of the "ladies" spotted the red record light through the partially open bag and we were chased out of the area by some scary looking minders!
