During the SARS epidemic everyone in Hong Kong started wearing face masks. Very eerie feeling to walk around and not being able to see anyone's face.
The old man with the tourist map (center) took it just that step further and donned a hair-net as well. I guess you can't be too safe...
This picture was taken towards the end of the period. To begin with there were hardly any people on the streets at all. When this picture was taken people were coming out of hiding but crowd levels were not yet up to normal.
