The end...

Et voila, voyage aux Etats-Unis terminé, nous rentrons le soir a Philadelphie en bus, puis je reprends l'avion le lendemain matin pour survoler le detroit de Bering et revenir a Shanghai :)

And that's it, wonderful trip in United States finished, we went back to Philly by bus before I took the plane to Shanghai, flying above Bering Strait :)
