Status Updates From Assignment in Eternity

Considering this was written before the race to the moon, it's pretty amazing. Heinlein speaks of fields of science that barely existed if at all. This is a collection of short stories. Gulf- starts out action packed and I really got into it until the main character goes to the ranch, at which point the story gets surreal and the end was just weird almost like it was rushed. 3 to go.
