US president Obama came to Europe this week for a number of "summits". The German part of the NATO 60-year anniversary was held in Baden-Baden in South West Germany.
Incidentally, my father works right across the street from where Obama's helicopter ("Marine One") landed, so he took a few photos of the helicopter arriving. Enjoy.
Update: Here is the gallery with the rest of the pictures, along with some pictures of an "Obama/NATO cake", one of the many products made in Baden-Baden for the occasion.
