I forgot to mention there will be no one around to do the plucking off the roof this time. It will be dog eat dog and most of the infrastructure will probably collapse and the cops will be protecting their own families. The military will be busy fighting a losing war and it will take a long time to get the National Guard in gear. In other words, you are on your own. It would be a perfect time for another Red Dawn, but I figure you did not need to hear that. So fasten your seat belt, it is going to be a bumpy ride and not everyone will survive, especially those who like gadgets. The grid will be down. FYI- there is a difference between pessimism and realism and it is not just about the fullness of the glass.
