I dug mine in Oakdale Calif, back in 2010, in a privy on a farm. Some Western collectors insist that it is Western, but without a label on a bottle I think its a crap shoot. If new York cures can make it out to Sacramento, I think a Detroit cure could be found in Oakdale, no problem.So Its probably from Detroit, although Nash is a pretty common name, so its crapshoot time, anybodys guess........Andy
