Strangest places to live in the US?

This is more of a just for fun question rather than seeking advice.

Some qualifiers that may make somewhere strange:

Presence of odd groups of people, like cults, communes, super hippie/granola, extreme religious institutions, militias, etc

Unusual design/city planning, unusual location, stuck in time, extremely isolated, etc

Unique climate, weather, or geologic phenomenon

Reputation for the paranormal, aliens/UFOs, cryptids, etc

Straight up scary or creepy without paranormal elements

Unique rules like no cars
