50s to 80s but it also made me think of a story my Grandmother wrote for the local newspaper.
Her first trip to Geneva, Alabama was by oxcart. She saw truly momentous changes by the time she was in her 80s.
Yes, biggest change from the 50s to the 80s. My father was born in 1896 so he knew of the first manned flight by the Wright brothers and lived to see the first landing on the moon. As a child, I experienced life without electricity and inside plumbing and we were still in a post WWII culture era.
My grandmother was a teenager when the Wright brothers flew the first airplane. She lived to see men walking on the moon only to see us abandon the effort. Saw the Shuttle. She died at 101. Heck of a lifetime.
