Do you have an underground bunker in your backyard? If you haven’t build one yet, this video will help to you to choose 1 of the 5 best underground bunker to survive the coming doomsday. For several decades’ prepping for a doomsday event has been a necessity for most people. This is very critical especially at these times when the future of humanity is uncertain in many ways. We have pandemics, social unrest and chaos all over and this means that we are living at very unpredictable times. For the older people, the events of the cold war are still fresh in their minds and the threat of a nuclear annihilation is still a big concern to them. When you mention a doomsday bunker, most people always imagine of a concrete underground room that has been filled with canned goods, bottles of water and other survival gear. The threat of a global annihilation in our days feels more real than even during the cold war. However, today’s high security shelters are not much different from their 20th century counterparts.
