Here is my lottery winner survive the apocalypse bug in plan. It's a 2000 sq ft underground bomb shelter. Walls are 1/2" steel plate with structural channel reinforcement. 12" of reinforced concrete around it and 24" over it covered by another 10' of soil. Enough supplies to last 6 people 7 years, and 3 years worth of seeds for planting. 6 people could stay here for 5 years then have enough seeds to start a food crop for 3 different years. There is 3000 gallons of propane for cooking and backup generators, but we are going to need solar power to last 7 years. The hole thing would be buried under the house.
Shelter: $1,500,000
Installation: $1,200,000
Supplies: $1,500,000
Weapons and Ammo: $1,800,000
