I agree. Get gold and silver with your money - now. Utah has already passed a law saying that you can buy things with gold and silver coins. Other places throughout the United States are also already accepting gold and silver as currency.
Guns and ammo are also a good idea to have. You'll want to be able to protect what you have. Also, don't advertise that you have any of this. You don't want hungry looters coming to your door.
Plant a garden on your five acres. The time to get seeds is now, not after the collapse. Get heirloom seeds, and learn how to do the planting.
If you wait until the headlines say economic collapse, you're behind the power curve. Everybody is going to panic when that happens. If you're going to do something, do it now. When the headlines read economic collapse, then, although you may want to dump the last of your dollars in exchange for something real, you won't be panicking, because you'll be ready.
