South mountain in Nova Scotia, Canada. There was (still is?) a family (the Goler clan) famous for poverty, sexual abuse, and inbreeding. A bunch of them were arrested for sexual abuse in the 1980s. Rumor has it, they inspired the Xfiles episode "Home".
Yeah, there's a lot of drunk oil hicks here, but I haven't seen much inbreeding. Though the last time I attended an event in Rumsey I couldn't help but wonder.
