How not to hide your stack... Two Swiss council workers had an unexpectedly lucky day while cutting the grass, stumbling across $123,000 worth of gold bars behind some bushes. http://news.ninemsn.com.au/world/8499149/council-workers-discover-123k-in-gold-bars
"Under Swiss law the council workers will be entitled to claim the 2.5 kilograms of gold bars for themselves if it goes unclaimed for five years." Should be worth well over half a million by then.
