We have hardcopies of all our important documents. That is all the prep I'm going to do until something dramatic happens since, as you say, it will be gradual.Good question, I guess it would depend on what you prepared.
I don't think that it will be as sudden and severe as what happened in those countries so there might be time to properly prepare. Such as the food shortage scenario that I described earlier.
I started this thread because I don't have all the answers and I'm hoping some other people will have at least some answers.
