Just the way my brain thinks (or doesn't think as the case may be), but I have never understood why. I mean it is cool and all, but think about all of the $$ that were spent toward putting a man on the moon and I think to myself - What impact has that had? Again, I think it is cool, and the guys that have gone up there have certainly been impacted (I got to spend an evening visiting with Charlie Duke about walking on the moon), but I never got it. Too much of a concrete mind.
