Heck, we can do that now. But the problem there is that ordinary people would have to learn things about tracking, natural camouflage and other techniques for evasion. On other forums, I found skeptics to be particularly resistant to wanting to learn about such things. On one forum I got, to paraphrase, "I don't have to learn about tracking to know a hoax when I see one", in reference to the 3-mile trackway found in Minnesota this last March.
So when we have provincial attitudes like that, learning will not occur, neither will enlightenment.
