I found this diary riding bikes to my grandparents' farm in 1994: it was dated 1979 and since it had really valuable entries about horses and boys, I held onto it. It's traveled with my other ephemera and me for 26 YEARS from Illinois to Texas to Idaho.
Today it's heading home! I found the author and owner online, and I just dropped it in the mail to her in South Dakota. I hope it brings her as much luck and wisdom as it has brought me!
