Yer... Cavepeople!
Kind of watched it... sort of... but I do get annoyed by programs that attempt to present facts in the style of semi-informed guesses.
Not always... but mostly.
The machete thing is my own obsession with large items capable of damage.
Like rocks and big thorny sticks. I understand rocks and thorny sticks... GPS etc. just goes over the top of my head.
