From the letters and my mom's knowledge of her parents' courting history, Grandma would get a ride from Nevada to Marshalltown (usually by hitchhiking) most Saturdays and Grandpa would take her back on Sunday evenings.
Grandma roomed with two other girls--one of which was her cousin Velma. Grandma and Velma would go "to the show" some evenings--a great way to relax after a day of typing.
