You can't find bigfoot

because you think within general concepts and not abstractions.In other words you do not see specific things among other things of similar nature.Wild animals and even domesticated ones do not think the way we do.If something new is where it was not when they last passed there.It will stop them in their tracks.So if you drop your pop can along a deer trail and then climb into your tree stand.Be assurred the deer will NOT step over or around your can or continue on that path.Why would that be relevent to your search? Because Bigfoot probably thinks more like them than us and he notices EVERYTHING!.So if you know four of his routes from point A to point B you can clutter three pathways[hopefully with bio degradeable stuff].Hang it from branches say.On the uncluttered path put your camera at ground level behind an existing natural obstruction to his vision.Take care to carefully intersect the spot you plan to put your camera and not actually use the path yourself. If not successful, just wait for Biggy to get creamed by those quiet electric cars we will all be driving soon.You guys will get better with more practise and less haggling!
