Well, it used to be a golf course. Now it's packed with more than 50,000 homeless and is known as "Sean Penn's camp," because the actor's humanitarian organization, JP/Haitian Relief Organization, runs it.

His sudden worry about my getting out of the car is a little unsettling ...... (Update: Sean Penn has written me to emphasize that he and J/P Haitian Relief Organization are committed to their work in Haiti for the long term.) "Already, it's been five months since we've gotten any food,"
