Look into geothermal HVAC systems.

If their account suddenly disappears, someone probably complained about them.
Which means they were probably a scammer.

And I would not bring anything to the police department.

Here is why: I know someone who found a small bag of something that she suspected was drugs. It was near a playground where her children were playing, so she did not want to just leave it there.

Uncertain of what to do, she decided to call the police department. After speaking with dispatch, she was asked to remain where she was. An officer arrived several minutes later and immediately arrested her for possession of drugs!

Hmm. Why do you assume that the Sasquatch are narcissists?

Not sure why you think its not possible. The problem is identifying them.
For example; in the final days with my ex, she admitted to me that she copies the emotions of actors on TV.
The reason this came up is even more bizarre. She began comparing our relationship to fictional ones on TV. There is apparently no difference in her mind.

A word of advice; no matter how innocent this type of a person may seem, stay the hell away from them. They will INTENTIONALLY do things to harm you, or cause you misery - just to get some perverse pleasure from watching you suffer.

There are many indications that previous advanced civilizations have existed. Virtually every trace of them was apparently eliminated by some type of cataclysmic event.
Note that there are currently 4, or 5 world wide extinction events that are "officially" recognized.
We are probably next.
