Thank You Flat Earthers!

So these guys (World's Last Chance) have taken out a full page ad in our local newspaper today using this as their headline, I can't find a copy online but this video appears to be what the text is based on:

Here's their web site :

They believe that the world is in fact flat, enclosed in a semi circular dome (which is why you can't fall off), and that the end of the world is near, you can get a gist of their argument here:

Apparently a faux alien invasion (hint: they're actually demons!) is part of the conspiracy.  It's a little hard to follow.

So for two days in a row I have been confronted with news regarding the coming apocalypse.  Is this a sign?  But what I really wonder is where did these folks get the money to buy full page ads in newspapers?  My dad's obituary was $1,200.

Anyone ever encounter this group before?
