If you want to protect your cash holdings, how about moving to a good place that was not inflated by the bubble, pay cash and buy a house you can afford comfortably. That way, a good part of your wealth is converted into tangible assets that can’t be depreciated by fiat money. With the remaining funds as safety net, you can live a happy comfortable debt free life. With the modern miracle of telecommuting, you can even work in far away places remotely.
I am very uncomfortable with holding large amounts in gold or foreign currency. Farmland may be good investment (people are always going to eat, even in recessions!), but I don’t know how to buy and lease/rent it to a farmer. If you think you can do some smart organic farming, that may be a profitable idea! (Even the Amish seem to have good life – at least in movies)
