No way! That's the reason the dad is digging up the front yard! He's making a fallout center shelter! He's was alive during world war 2 and was worried about them dropping more bombs in the Vietnam war like the german did in WW2! It just goes to show you what war does to people. Makes them paranoid. All they can think about is building extra precautions because their afraid that whatever happened in the first war. It's just sad.
