My little desert ghost town..
..has antique marbles buried in the sands of every old abandoned house here. The town began existence during the late 1800s. Was going great guns by 1914. Had it's own railroad by 1921. There were over 5,000 people living here long ago. There's only a couple hundred people here now and fewer every year that passes.
I was helping to clean the sagebrush off the yard of a house built in 1930 a couple years ago. Began finding antique marbles but nothing special. Then an older man approached me,said he had heard I'm interested in marbles. He handed me a marble he had picked up off the sand a few feet from where I was standing. It was neon yellow. I went home,aimed a blacklight at it and it lit up like Las Vegas. It was an Akro Agate. I would estimate from what I've found already that there's,conservatively speaking from 50,000 to 100,000 antique marbles still buried under the sands of my ghost town. We get hurricane-force winds here that blow away the sands and reveal them.
