Sooo…what you are saying is, all a super villain would need to do in order to hold the east coast of America at ransom is: 1) Buy one of the Canary Islands. 2) Cut extensive tunnelling and lay rollers, in specific directions and at the proper incline. 3) Wire up the support columns with explosives. 4) Unleash a landslide if demands aren’t met. 5) Profit.
