The Chicago stockyards are my favorite of the 11/30 listed. The rest are an interesting mix of crypto-conspiracy and modern mythos and I like that a lot. There are a couple of things that come to mind to add to this.

Australia and the dreamtime
Devils Triangles and missing cruise ships
Dinosaur cryptids or isolated locations with dinos.
Cold War era simulations, like the American city replicated in Russia to train spies
An Ember/Matrix like buried vault city Go to Comment
