Lack of military grade technology will yield the same results that have been produced so far. It's always been something ........ the woods are to vast, not enough boots on the ground, need better technology, Bigfeets are super rare, stealthy, strong, smart, stinky, blah blah blah all excuses imo.
But the discussion is valid, what if someone were to finance a Bigfoot project, you name the price, you've got 6 months to produce a body. If you fail...... you pay back all money spent plus 10%. If you succeed the backer owns all rights to everything and you'll get 10% of the profits.
While I don't think you'll be kitted out with military tech, you'll get to go on a dream shopping spree, but you will definitely be on the hook for your convictions.
So what would it take to prove that Bigfoots real? What would that set up look like and cost....any body up to the challenge?
