Christian: of course you will be running the Chicago 2010 marathon as your next fall marathon. Not only are Paris and Chicago jumelée (i.e. sister cities), but the Dollar is so conveniently falling vis-à-vis the Euro that you'd get all this done for about a Euro and a half by the time the race happens. Moreover, 2010 is going to be Debian's US year anyway. I crammed my two European races into two four day trips which I won't exactly recommend, but you do not need ten days either. Lastly, I cannot promise you many interesting cheeses but there are at least a few pretty tasty beers to sample. À bientôt à Chicago!
