Yes, I will definitely be leaving.

Thanks for the advice.

Wow, thanks for the insight, I appreciate it.

I like your Strega theory. Perhaps the woman that went missing in the 50's became corrupted by some Dark Power she found in the caves and is now a Strega-like monster, practicing ritualistic magic on children that wander into the cave.

The Merrow's theory is solid too. Well researched, definitely plausible.

I think the locals call it a ghost because they have no idea what it could be. The name the campers gave it, "The Backwater Banshee" may come from the fact that it screams like that, plus the alliteration is pretty catchy.

I'm worried about this mark on my house? What could it mean? Should I try to remove it or just move away?
