OK.....I'm gonna' throw my .02 in here too!
His family has a "compound" about 15 miles from my house. it's in central MO and was built in the mid-late 70's. He (Jimmy) owned the land since thw late 60's and it consists of 700+ acres.
My family has been in the Masonry Construction business here since the late 40's and my Father did the Brickwork. I worked there a few times through my years with the company and I do know this......there is an area about 50'X50' with a 8' - 10' high wrought iron fence surrounding it completely. Working there was actually pretty fun at times........they brought beer out many times for us after work and had a huge party when the main structure was completed around '78 or so. At that time, his Son and 1 Daughter were the main people we'd see there as far as those we knew, but there were always at least 10 - 15 people there when we'd work therefore you never even thought of going to check out the area mentioned above although it was discussed often!
I was there last about '85 and did some more work on a secondary house (only about 3000 sq. ft.) and the same area was there just as it was before, very well kept with flowers and small bushes but nothing else visable.
Well, I suppose by now you can figure what my thoughts on this matter are......I have no idea if I am even in the right ballpark (LOL after above comments) but many people around here seem to think so! Hell........I probably shouldn't even be writing this...........
BTW; for anyone whom thinks this is just completely a story.......it's all a matter of public record as far as where the compound is and when the construction permits were issued........it's there and it's very close to where I ended up building but, I have no desire to go try and find out if I'm correct! The whole damned place was and is spooky.......wrought iron fences and all!
