There is one in HUTTO, just east of Austin, Texas off hwy 79

They park a freight train on tracks so you can not see if from highway

I heard this rumor... so...

We drove out 79 heading east , until just outside Hutto we saw a mile long freight train just parked, we stopped, hiked over walked between the cars ...

and sure as shit there is what looks like a high school with 10' double fence around it , razor wire whole set up

Like a county prison... but just a few trucks in parking lot, maybe 4-5?

100% true, if you live in Austin follow direction above to see for yourself

** i have NO idea WHAT this place is? but it fit the description
