Bois de Boulogne - La Defense business area

As I was crossing the park, I saw that the helium balloon "Observatoire Atmospherique Generali" was flying today, so I decided to take a ride.  It's held by a cable, so doesn't go anywhere, but it does offer a good view of Paris, from about the same height as the Eiffel Tower. 

This is the view west of the city, with the big Bois de Boulogne behind the 16th arrondissement just across the Seine river, and the La Defense business skyscrapers on the far right..
