Post apocalypse I think we&#x27;re going to be down to mail-order rather than that we&#x27;ll use the internet, unless those carrier pigeons will be used to implement tcp&#x2F;ip as well. I&#x27;m half tempted to figure out what the amount of gold is that a carrier pigeon could carry. Storing $10M in cash would guard against a short duration (3 months?) collapse of the banking system, storing it in gold is to guard against something of a completely different order.
