You’ll be laughing last when you have water and nobody else does.
It’ll be a different story when everyone comes begging to you for water. Not so funny after all, is it?
I read an article the other day in a Dallas newspaper about those people who are living like "normal people", yet are making preparations to survive if something happens. Several people would not give their names. They didn't want people to think they were doomsday kooks, and they didn't want people knocking down their doors when TSHTF, either.
