On Saturday, July 16, 1966 a happy and healthy seven-year-old girl named Ruth Ann Miller was playing with friends. She fell down an abandoned 1-mile deep vertical mine shaft in Calumet, Michigan in Houghton County (Upper Peninsula)
I'm seriously puzzled how the oldest concrete road in Michigan is not only in pretty good condition considering it's almost 120 years old, but is in better shape than most of the roads we have over here in Kalamazoo.
