Orlando Opening up 'Slum' Themepark?

ORLANDO, Fla. (Reuters) - Habitat for Humanity, the nonprofit group that builds low-cost housing, is opening an unorthodox "theme park" at its world headquarters this week designed to give tourists a look at the world's worst slums.

I guess it's an ingenuitive way of getting people to come out and volunteer, but attracting tourists?!?! There's something very dirty about that... (via BoingBoing of course!)
