Colleen and Chris Otcasek from California were looking for a new house, and finally bought one in Woodland Hills.

They were brave enough to venture and go down into the bunker, where they have found a shelter for a family of four, stocked with everything they would need for up to three weeks of staying. They found out that it was built by Alvin Kaufman – a self-taught nuclear engineer, who worked for the US Government in the 60’s. It explains why he knew every danger of the nuclear attack and prepared the shelter accordingly – with several sleeping areas, a water tank, a hand cranked air filter and enough food and other supplies.
