Speaking of Zip locks. A year or so after I moved to NC, hurricane Sandy was determined to make land fall in NC. Although I live a ways inland, it was thought that it might head in. Anyway, the pre-storm panic hit and people were buying bottled water practically in truck loads. I bought a box of Gallon Zip locks and filled them with tap water and neatly stored them in a cardboard box. Sandy did damage to the outer banks, then continued up the coast to the New York, New England area. I knew that pouring water out of a Zip lock in a controlled way would be challenging but I happily never got to test it out,
