Factual error: At the breakfast table the father is reading the Rocky Mountain News newspaper, which is quarter folded (like most papers) but the RMN was always a bi-fold paper, like a large magazine, folded down the center. The RMN went out of business a few years ago, but they always used this format.
Factual error: On Saturday morning Gwen and Finney were watching cartoons. This was the day after she spent the night at her friends house which was a Friday night. The cartoon that was on the TV was Davey and Goliath. This cartoon only aired on Sunday mornings.
Suggested correction: "Davy and Goliath" aired on Saturday or Sunday mornings, depending on the TV station. And, according to Wikipedia, it "premiered in syndication on 2/25/61 as a Saturday feature."
