Not to pick on your thesis, but there have been spots like this in Florida for decades. I used to fly in and out of the state a lot back in the 70s and 80s and I saw dozens of them. Why the developments stopped after site improvement, I don't know, but I do know it is nothing new.

I have to agree with Ditto here. I went to college in Florida in the late 70’s to early 80’s.

We would find developments like this and have large bonfire parties out in the wilderness.
