Just to save everyone some time, there are no treasure maps, there are no hidden caches of gold from the Civil War. There's a rhymed set of clues that an eccentric millionnaire had published, implying that he had, in recent times, hidden a cached of gold and jewels. Very recently some joker thought he'd cracked the clues and wound up dying in some hot spring in Yellowstone.
Hadn’t that newfangled railroad thing been invented by this time for the government to ship high value cargo?
