Aside from all the coffin jokes...did anyone else notice that it has to be placed on a concrete foundation and must have access to a power supply? Ok, if the electricity is what is going to open this thing up..and in a Tornado, Hurricane or Earthquake..the power is the first thing to go...man I would not want to be in there. Hopefully there is a manual opening feature...hopefully. <img src="/images/graemlins/confused.gif" alt="" />
