Back in my teens when I lived in Dover (of the Straits, not the evolution/creationist debate), the Flat Earth Society had its headquarters in the town. Now and again he would publish a bit in the local paper about the evidence for the flatness, using the horizon on the sea and its position against the cliffs when viewed from different heights. The society was, like Earth in the Hitchhikers' Guide, mostly harmless.

I gather that on his death the movement moved to a trailer in the States, and has become religiously nasty.
