^ Ah ouais, c'est vrai. There are some kind of inclined streets over the 20th arrondissement too... Ha, you might be aware of the city's topography better than I am.
Nothing much to do with San Francisco's sloping streets anyway. Biking over there must be a bit of a challenge, even though that's not the Alps stages of the Tour de France.
I just guess a lot of US citizens would be interested in visiting Suresnes because there's the
US military cemetery upon the hill. That's to pay tribute to their soldiers who died for World War I on France's soil. You know, the Americans are usually "patriots" and find these things important, which is normal after all.
Visiting the site of the memorial would give them an opportunity to enjoy the view over the city, which is a plus.
