Rant: Finding Bigfoot

Finding Bigfoot is a documentary television series that is on Animal Planet. The program follows the Bigfoot field researchers organization in their search for Bigfoot. I don't know if many of you have actually watched a full episode, but it's a bunch a baloney. An episode usually starts off with a few random eyes witnesses who leads the "Bigfoot Searchers" to a specific location. Once they have their location, they set-up a bunch equipment that will help them gather evidence or possibly capture a Bigfoot. In the middle of the woods, one of the crew members will send out a so called "Bigfoot call" to see if they'll get a response. At the slightest sound the crew will begin to panic causing the show to go to commercial break. When the commercial break is over, the sound is usually some small animal or just the wind. 

I think anyone who's searching for Bigfoot is basically wasting their time. I believe if we didn't find Bigfoot by now, then we never will. Bigfoot is describe to be a very large creature, what are the chances of us not finding it by now?
