Standard hoaxer "blame the victim" stance. The hoaxers conceal the location and other evidence, then blame the targets of the hoax for it. You should be asking Bipto on BFF for the exact location, list of participants, confirmation of the property owner, etc. - but you won't. I take it nobody on the BFF has even bothered to ask the location. If that doesn't speak volumes, nothing does.
In those tapes offered as "evidence" on the TBRC site for 2011, what you hear is loud cicadas and an occasional noise, the loudest two of which sound very much like metal objects contracting in the cold. My five-gallon metal gas cans make amazingly loud noises at night, and again expanding during the day.
I'm still open-minded about the exact location - I might not have located section 5 correctly, and they may not have been telling the truth about the property owner, just like not telling the truth about how far from roads and houses the site is. There is no place in the entire state that is 20 miles or more from a house.
Here is the population density map for Oklahoma:

Observe that there actually is an area in Oklahoma with a population density of less than one person per square mile - in the extreme NW of the panhandle. In Southeastern Oklahoma, the most sparsely populated areas of the Oachita National Forest still has between 1-10 people per square mile.
You cannot truthfully say that nobody lives for 20-30 miles. The person who is making this easily disproven statement is also in charge of concealing all the other important evidence.
From the tapes, these sound like people that don't need anyone to hoax them. They hear a sound in the night and they're making recordings of themselves cowering inside. Brian Brown asked this question of his own group: "why didn't you look out the window". He claimed they can't. That is trivially untrue.
Can't look out the window.
