Yeah, if there are bottles it's very probable that homeless people frequent it, especially with you hearing noises coming from it.
I see... ๐ค Never see someone go there tho.
Let me know if you ever do end up exploring it. Maybe you could even write a post about it. ๐๐๐โจ๐ค
Sure, I'll take a photo there and maybe get a ghost photo ๐. No promises yet~
!LOL
