Hi retgi -
I'm not so sure if "this is the big one", as Glenn suggests (and I'm a fan) but some of his suggestions make sense. As you probably know, one of his messages is to pay off your bills. If you have a mortgage, car loan, etc., pay it off if you can.
Food storage. Glenn's a morman and they are big on food storage. If there's a run on the banks at some point, you probably won't have fully stocked grocery stores.
For that reason you probably want some guns and ammo because those who did not prepare, will be looking for your stash. Gold and silver, sure, and as an investment, how about real estate? Like gold and silver you probably want the physical rather than the paper, so you don't want gold and real estate stocks, but rather coins and land. Companies can fold, but gold and land will always be there (except on the CA coast in 2012)
Agriculture would be big. There's companies like Monsanto or Potash that would likely flourish. Jim Rogers had said because of the potential financial collapse, the next wave of rich folks won't be on Wall Street, but rather farmers.
Again, I'm not sure this is going to happen, but it never hurts to have some preparation. Like the year 2000 computer glitch that never happened, or if the Mayans happen to be wrong

, life will likely go on and if you happen to have some food in your house, and some gold and land in your portfolio, along with Ag stocks, no harm done.
