Signs posted around Southern California's Big Bear Lake read: ATTENTION CAMPERS: Due to increased Satanic Cult activity in this area, camping is not advised until further notice. SEVERAL PETS HAVE BEEN REPORTEDLY SACRIFICED IN SATANIC RITUALS.” (source: Boing Boing)
You guess it! The signs are fake. Well, they're real signs but they weren't posted by the US Forest Service.
I like this for the overall weirdness, of course, but also, I have spent time at Big Bear, being from Southern Cali. So, always interested in the latest devil in the woods stuff.
