Her lessons offer reason for part of the fun, then the camping episode involves the admiration of a country boy for the girls in general. There is a little plot concerning an option on an oil gusher, which through Mary's carelessness father almost loses, but she saves the day by getting him to the lawyer's office in the nick of time to take it up. It is up to Mary to race with a high powered motor, but by clever manipulation she wins. Fun races through with the cars and is at high speed when the country boy attempts to follow his ideal and present her with a bouquet. As a reward for her daring, father presents Mary with a regular car in the end.
