I posted this on Justin's site then saw that you were looking for info so I am just going to cut and paste what I put on his site. Maybe some of it will help:
Everyone wants to know where the entrances to the tunnels are. The problem in answering this questions is, the entrances are for the most part, covered up and concealed now. You want to know where an entrance is? The Cain Center. There. There is one answer for you. Yes, I have personally been to it. At the time, I was young and stupid and did not travel down the tunnel, fearing satanic cults until I grew up and realized that was all a smoke screen for what may really be going on.
The year would have been somewhere around 1983. Like many of the young people in that small town, we were told that the tunnels were used for Satanic ritual (which sounds pretty ridiculous now that Ive studied Satanism). I was taken to the entrance, which was the land that the Cain Center is on now, but at the time was a construction site. The parking lots and drives leading to them had been laid because thats what we drove on to get to the site. We had to stop the car in one such parking lot and walk on foot to the entrance which I guess was probably about 50 feet away from where we parked.
At the time, the entrance was concealed in thick brush. Once at the entrance, it was very easy to tell that this was not some primative looking tunnel used by the underground railroad, or satanists for that matter. This was a huge, elaborately masoned bricked tunnel. It was large enough to easily drive a vehicle into, and too large to be a sewer. I remembered being surprised at how well made it truly was. It was not made of the red/brown virgin rock from Fullers park, at least from what I recall of it.
Years later I tried to return but could never again find the entrance. However, here was this MASSIVE recreation center spanning some 38 developed acres where the entrance used to be! That is massive! All that for a little town with a population of maybe 5k-8k back then. Strange, huh? Google satellite it sometimeits MASSIVE!
Ive been to Fullers Park. We used to scare each other there to pass the time. Ive seen the graves and the well (yes, the well does/did exist). It didnt strike me as anything odd. The cages, not too odd either. Ive never seen a tunnel entrance nor had I heard one existed there until nowadays. I have never heard that the tunnels formed a pentagram shape either. I have heard that the pentagrams above ground are spaced in such a way that they create one larger one if viewed from the sky.
I have been to the pentagram too, at least one (there are supposedly 5). I stood in the middle of it actually. As a 12 year old (who had a strong interest in the occult), I made a point of trying to memorize the address. Since I have become and adult and started my own research project on Athens, I tried to return to the pentagram about 5 years ago. I could not find it (or the house I remembered it being at). I am unsure if my memory failed me in retaining the proper address, or if the pentagram was just simply gone.
The address, as I recall, was 2526 Palestine Hwy. There were huge gate pillars in the front (but the gate was never closed), much like the ones at Fullers Park. The house was set far back from the Hwy and it had a huge U-shaped driveway. The pentagram was between the house and the street on the inside of the U-shape. The pentagram was made from a reddish brown brick or rock (could have been virgin rock).
I viewed Justins documentary videos on youtube. I was excited to hear there was another Athens project besides my own as I never finished mine, and I was very close to handing my research over to him so that it would help. But once I saw his Wiccan source on the video, I lost all respect. I hope he finishes the project but from a more professional standpoint. Please find a better Wiccan representation than a crude lady in a KORN t-shirt. (no disrespect to KORN of course, LOVE them!). But Wiccans deserve more respect than that.
I contacted several professors at HCJC during that time who were more than happy to tell me of the history of the tunnels as they applied to the underground railroad. I also ran across a lady who wrote for the Tyler newspaper who had done research on the tunnels as well. So the tunnels DO exist. There is no doubt. The problem is getting to them.
I interviewed a few people who lived there and who swore to the fact that the archived newspapers had been altered to remove information vital to the reasons they exist, including one murder.
Now, some things to think about for all of you conspiracists:
The small, sleepy town of Athens, Texas (pop. 5,300) has the enviable reputation of producing more millionaires per capita than any other place in the U.S. http://sportsillustrated.cnn.com/vault/article/magazine/MAG1069698/index.htm
The Bushs maintain a residence nearby http://www.athensreview.com/opinion/local_story_077224005.html
The rich and powerful have their own playground called the Koon Kreek Klubironically, KKK. http://www.forbes.com/2006/02/17/hunting-cheney-whittington-cx_kdt_0217cheney.html
Athens has a huge concentration of freemasons. (my personal knowledge, being my grandfather was a 32nd degree mason)
Ive read that Athens is a busy drug highway pitstops from Mexico into the US.
There is a huge good ol boy network there with references of people being murdered and also injected while in prison.
Satanists dont go literally under the ground to perform their rituals. Cmon now. They have plenty of places above ground!
With those things being said, one may want to research underground tunnels in reference to government and also to military black ops projects. And, if lets say, the powers that be werehiding.something.in the bible belt, what better way to keep it hidden than to perpetuate big evil satanist rumors.
And if youre still stuck on the satanic rituals then research Bohemian Grove Rituals.
Just my two cents.
