Kidnapping incident by a mysterious alien Frequent area

There seems to be a place where a signboard is believed to be banned, as alien abduction cases by aliens are occurring frequently or abduction of UFO abduction.

Although it is a very mysterious signboard, I am very anxious what is happening in the place where the signboard is set up.

Pictures are as follows.

Picture with signboard up. It seems that UFO is prohibiting people from being raised by any means.


What is going on in this street from 9 o'clock in the evening to 6 o'clock in the next morning?
