The author believes that a life event, no matter how significant, only exists if recorded. "Marching Through Time" begins with a poignant letter to her Crow Indian great-grandmother, Kills the One Who Herds the Horses. Her own grandchildren are preschoolers, so she describes a seventy-year life that is extraordinarily different from what theirs will be. It ends with a plea to her own descendants, born and unborn, asking them to give her a future by holding her book in their hands. Early years were lived in a log house in Montana's Rocky Mountains; she describes coming of age in a small cow town during the l950s. Read vignettes of embarrassing moments like falling downstairs in a first pair of high heels or her first and last horse-ride. After two years of college, a forty-eight year marriage follows. She describes life with her three children; two of whom are now dead, one by suicide. There are entertaining stories of teaching preschool for nineteen years, home-exchange travel and retirement bridging two centuries. Smile or shed tears while reading the adventures and difficulties of a person who had some extraordinary life experiences while marching through time.
