Are you prepared for major catastrophe?

Sure, you can stock up on emergency supplies but if you want real survivalist training, there are some truly over-the-top experiences out there.

A company called Maverick Business Adventures is part networking group, part high-adrenaline experiences.

In its Covert Ops course, you’ll actually get survivalist training with Green Berets and Delta Force instructors.

We’re talking rappelling from a helicopter to the jungle, hunting for your food, and learning close-quarters combat.

Another company called SpecOps has adventures that are designed and led by U.S. Special Forces veterans. They’ve even got couples’ programs to see if you—and your relationship—can survive in the great outdoors.

And last but not least, if you really want an insurance policy when the you-know-what hits the fan, there’s Vivos. This is a planned network of secret underground bunkers.

Each one will shelter 1,000 people, with food, water, fuel, and supplies to last at least a year. And a fractional ownership can be yours for just $50,000.

Hey, I told you these were over the top!
