I would go beach.  Sandy's.  But das me.  We'll get a little bit more time than what is commonly known because the radars associated w/ the launchers or launch sites would fire up before any launch.  That's why you hear on the TV, "There are indications that [fill in name of idiot nation who hates us & has missiles here] may be preparing to launch another missile..."  That's the met radars firing up and checking the launch parameters.  The electronic version of licking your finger and holding it above your head.

I'm Roman Catholic so our doctrine relates that as long as you are sincere, really sincere, in asking for forgiveness of all your sins even up to the moment you breath your last breath, your sins will be forgiven.
