I had always heard that if something really bad happened on Earth, Denver International Airport is where all the important people would hide. Who knows if that is true, but what is true is a sanctuary that is being built in our state for something similar, only it's for anyone who wants to be a part of it.
According to their website, Fortitude Ranch a 7,000 square foot shelter and lodge. Log buildings on both ends are connected by buried, underground basement rooms. The 120 foot long basement has over a dozen rooms to protect members from radioactive fallout. There are also member rooms in the log homes, plus kitchen, bathrooms, and a beautiful upstairs living room with fantastic elevated view of the neighboring George Washington National Forest. A large wrap around elevated deck is a great for both enjoyment in good times—and a guard platform for bad times. The center basement is covered with three feet of earth.
It costs $1,000 a year to be a member, but when the zombies come you'll be thankful you did it!
