Why go to the Moon?

I'm on travel today, which is going to take all fracking day, so I will make this short. I gave my Moon Hoax talk last night, and as usual I got questions about NASA's return to the Moon. Probably the most important aspect of this question is "Why"? Why go back? I have my own thoughts about this, and I've written about them here on this blog. Not surprisingly, NASA has a web page listing their own reasons, but their statements are rather lofty, and not terribly meaty. However, others have written about this topic too, like the Space Frontier Foundation and two authors at The Space Review: Mark Huang and Jeff Foust. Read those, and then tell me: What do you think? Just a little Friday free thinkin'.
