Given the amount of carnage on The Walking Dead, it’s probably not surprising that Game of Thrones author George R.R. Martin is a big fan.

In an interview with Entertainment Weekly, Martin revealed an (obvious?) way to survive a zombie apocalypse:

“Castles!” the author told EW. “Whatever is happening in the United States during The Walking Dead, I’m sure they’re a lot better off in England because they’re in castles. If they had any brains, they’d go to the existing castles and reinforce the walls. They can patrol on the bulwarks. No way is a zombie [getting through]—medieval seige armies couldn’t break castles with conventional artillery, and zombies don’t use artillery. Zombies don’t build trebuchets. They don’t build siege towers. There is no way they can break into a well-defended castle.”

On its face, it sounds like a good idea. Now, granted, a prison is no castle, but it’s close, and we all saw how well that worked out — but maybe the chain link fence is more to blame there. And the Governor. But that also brings up a valid question: What about humans attacking the castle with artillery??

Do you agree with Martin’s advice?
