The smell of the city

Gawker has created a new way to explore the big apple - the New York Subway Smell Map - hover the mouse over your local station and find out if it smells of alcohol, body odour, perfume, food etc. I'll be in Manhattan from Friday next and I notice that my local subway station hasn't got an olfactory tag just yet - maybe I'll add mine before I leave? Union Square is particularly aromatic have to say...not quite what I experienced last time I paid a visit ...Andrew Taylor asks the really interesting question though:
"Will seeing other people's experiences allow us to engage differently with our environment?"
