Here are the promised Bomb Shelter pics. They are only TEASER pics. The ACTUAL Bomb Shelter picture will come later. Consider it a trailer of sorts, a preview, the inside flap.
Hatch (submarine-like entry/exit) in the backyard. This is a bird's eye view of the hatch. Anyone watch Lost? I don't, but people have told me it reminds them of the show. Alternative entrance is in the garage floor, literally the garage floor. That's the one I use.
