My father would always tell me that locks and keys were to keep honest people out. I have lived in NYC where you had to have a rhino in front of the door so folks would not enter but at some point in the past, a lock and key would have done the trick.
I can’t imagine there was much left in the Keystone Mines in Amador City in 1915. This is another possible example of “mining by assessment.” This was a simple premise wherein the folks allegedly working on the mines kept hitting their investors for more money while actually delivering little more than a “dry hole.” Lots of mining fortunes were made this way. Pretty certificate though.
So I am sending this one out to you my friend. I wish you health, life, and money, and the time to enjoy them all.
