Considering this is what happened on the other side of the county, I was preparing to spend the entire night in my storm shelter, or as my friend, Gina, dubbed it: the Tomb of Doom.
The back flooding issue has, hopefully, been rectified.
I have a 4" ventilation stack on the bunker, but I wondered if it was sufficient for a long 12 hr stretch. Online research uncovered a 1960's era experiment on the matter. Remember, this is the time of the Cuban missile crisis when atomic bunkers were popping up everywhere, a time before guidelines were adopted for the use of animals in experiments, a time where an Air Force serviceman was just a guinea pig.
It appears that without an intake and exhaust stack, I don't have enough air circulation in my shelter for an overnight sojourn. Apparently.... it wouldn't be a good idea to fall asleep in there...
Knowledge is good.
Having an invitation to overnight next door in a big sturdy brick house is better.
The little piggy who lives in the straw house gathered up her posse and spent a very uneventful night at a house where they serve homemade strawberry ice cream.
