Here is an interesting story regarding a small gold and silver mining town in eastern Ontario called Cordova or Cordova Mines. The ghost town is located 9 KM north of Marmora on Peterborough Road #48.
Like most mining communities, Cordova was 'officially' dry and the refreshment parlour served only non-alcoholic beverages.
However legend has it that just north of the village there was a mobile saloon, situated on a road that was also right on the county line between Hastings and Peterborough.
Word travelled fast in those days and whenever the authorities approached, the saloon would quickly be wheeled over from the Peterborough to the Hastings side of the road. I bet if somebody to day could narrow down this location with some additional research, then they would have a “field day” exploring it with a metal detector.
