That Billy is nominal.
Take a look at this baby for the real story.
It's really up to you, follow your instincts. The conclusion I came to was that cash in the bank was losing value very quickly against most stuff like tax, fuel, houses, food, gold of course, regardless of what GBrown says. The CPI is not so much dishonest as useless!
So truthfully, I decided that cash was definitley more risky than gold. I think cash is at nearly as much risk as property right now.
