Re: Interesting timing ....
CdeG
I remember my first time flying into there - my first thought on entering Arrivals was "what *is* that smell"?.
Having a somewhat sensitive nose[1] can be a pain at times and the Arrivals hall at CdeG was one of those. None of the other airports/train stations near Paris smell anywhere near as bad.
[1] Really bad eyesight, really good hearing and sense of smell.
