I am not sure why you are arguing this with me. Let me refer you to Grover Krantz and Jeff Meldrum.
-----------------------------------------
If track casts were physical evidence then Grover would not have been road hunting at midnight with a rifle.
There would have been no need for it. And that's exactly why I'm arguing with you. You ignore his most important core message that we need to score a touch down.
This defacto discovery crap needs to be dropped, and people need to get back to work. It reminds me of participation awards at little league games.
There is not Verifiable, Testable, Repeatable evidence in regards to BF tracks because there is not a Verifiable, Testable, Repeatable physical BF foot to compare it to.
