What an interesting story, my dad used to tell me about an old American cowboy who lived up in Omeo in the 1930's, who was supposedly a very well known (and supposedly wanted) gun slinger who'd disappeared in the US and travelled to Oz figuring that nobody would come looking for him "Down under".
I don't remember enough of the story to say much more, but dad told me that this old guy was the real deal, and he'd paid for the first "Golden Age Hotel" with gold bullion, which he seemed to have a lot of, interestingly. Dad moved back to Melbourne at the outbreak of WW2, and never saw or heard of the old guy again, and none of the locals could remember what happened to him either. Another mystery that'll probably never be solved.........
