There's no call to be homesick if you're an American in Paris. In addition to the 50,000 or so other Americans currently living here, the city is rife with reminders of others from days past.
For starters, there's the street names:
Then you got your statuary...Washington, Jefferson, Franklin in various poses with and without the Marquise de Lafayette.
FDR has his own subway stop although sometimes I overhear American tourists calling it Teddy Roosevelt. (C'mon people, think about it.) Originally, this stop was named Rond-Point des Champs-Élysées.
And while you won't find a "George Washington slept here" marker in Paris (because Washington never got further from home than the West Indies), there are the moral equivalents.
