The coach had a cousin who married a Chilean and they lived in Chile. Both were enthusiastic basketball fans and when word got around that the wife had a cousin in the United States who was a basketball coach, Mr. Vandiver was issued an invitation of an all-expenses-paid trip for the summer (winter there) to come to Chile and coach a team ( or as the letter states, at least six teams). He writes that the teams are much different, and he must have coached boy and girl teams both and traveled extensively to play games, all the way to the "H.S." tournaments that would start within two weeks of the writing of the letter.
The letter details what his trip was like. Mary Evelyn said when he returned home and got off the plane, he was wearing a big cowboy hat and a colorful vest, both gifts from his friends in Chile. She remembers him bringing home souvenirs and gifts for the family, in particular some fine wool fabric that Chile was famous for.
Maybe it will stir some memories and someone else can add details.
Mary also said someone (probably from Chile) gave her dad a scrapbook/photo album bound in leather with photos from his trip. Unfortunately, she hasn't seen the album since her mother died. But she promised to ask her sister, Golda, if she has the album. If found, we will add more details.
Thanks to Mary Evelyn and Cynthia Mink for obtaining and sending the information. Letter courtesy of Betty Massengill.
