from fearnet.com: Partially built in the late ’70s as the site for a computer factory (which never materialized), these surreal abandoned domes in the remote desert town of Casa Grande, Arizona have a decidedly spooky aura about them. That supernatural vibe has allegedly drawn the attention of visiting occult practitioners, who are rumored to have conducted rituals in the crumbling man-made caves, some of which are shaped like UFO-style saucers or caterpillar-like formations.
