Guillaume has accompanied Mr Jeannot Krecke, Minister of Economy and Foreign Trade, for a working visit to the United States of America 16 to 19 November 2009. The Luxembourg delegation met with leaders of DuPont de Nemours in Wilmington (Delaware), Guardian Industries in Auburn Hills and Delphi Automotive in Troy (Michigan), and Goodyear Tire & Rubber in Akron (Ohio), thereby strengthening the linkages with the branches of parent companies of these American companies based in Luxembourg.
Transatlantic flight + Ohio + Delaware + Michigan in 3 days + return transatlantic flight = an exhausted Hereditary Grand Duke. I hope he stopped in to visit Louis and family in Florida before he returned home.
Sadly, this information was not known until after the visit was completed - as usual.
