DON'T TRUST THIS MAN!

he's not wrong

Unless you're not a man.
I keep debating whether the mines would be the best or worst place to be in the event of the zombie apocalypse.
My gut tells me that as one of the most secure facilities on the planet that it should be one of the best places to be.
That said, my head tells me that if just one infected person breaches, then it's just a giant, captive buffet.

Oh, and I've also considered the very real possibility that it could be ground zero of said apocalypse.

Here is a good summary of what the mines are now.

There are all sorts of music master recordings stored there, among other things.
A couple of years ago the wife and I went to dinner at the local brewery. As we were entering we noticed the gigantic SUV limo parked out front. I joked that Donnie Iris must be inside.
Nope. It was Ozzy. He was there with Jack to film an episode of whatever show they were doing. Jack arranged for his dad to go into the archives and listen to some of his old, unreleased recordings.

We now need to come up with an Ocean's 11/National Treasure style plot to steal something priceless from the mine.

I'll start digging a duplicate mine!

Watch out for pookas and fygars.

they are the worst!

If you have an old bicycle pump, they shouldn't be a problem.

A licky boom boom down.

Okay, my special order garment has arrived, so I will be packaging up my LPC Secret Satan tonight. I would feel more guilty, except that I really don't.

I believe the answer to all of that is "yes."

It would make a great setting for a Living Dead film, actually.

Actually, now that I think about it, there WAS an underground research facility in one of the Living Dead movies, wasn't there?

EDIT: Yes, Day of the Dead is the one I was thinking of, and it was shot in the Wampum mine. Not the mines Harpua and I were referring to, but also within our general area.
