I honestly think we may have found out some shit we didn't really want to know - or at least that the government didn't want the public to know. I think we've been back, but much more covertly.

I can't begin to imagine what the truth might be, but it makes exactly no sense for a species that likes to settle and control every patch of viable land it touches to visit someplace like the moon and never return.

I can't imagine that we are staying away (or keeping our visits secret) without a very good reason...
