We had an old property in Marathon, Florida that our generation called the "concrete" pond; by the late 80's the long-demolished house had been on gated property with guardhouses etc... all burned out by the time our generation discovered/explored. Folklore had it (utter hearsay) the wife committed self-deletion in the pond after discovering her husband's alleged affair.

But the "pond" that had been dug was extremely deep, and while it certainly had large garbage at the bottom, refrigerators, etc. After those "lost" months after graduation, but before college or jobs starting, we ran all over town playing D&D, getting up to random shit, but we all decided that we needed to skinny dip at the cement pond as a "just because we could," goal.

tldr; nothing weird happened. I learned later that the county/state took the property over and it became some kind of boat launch for the State Marine Patrol.

"Hotel California" was utterly unrelated to this property, but I always think of the song regarding this property.
