Yes, my sister is an example of this. She attended a private, all-girls high school in Pennsylvania. During her senior year of high school, she made it on the junior varsity football team of the local public high school in South Jersey. However, due to her hectic schedule (that year, she took 3 AP courses and worked on the weekends) and the long distance between the private, all-girls high school she attended and the local high school she played football for, she was exempt from attending the practices. (In lieu of practices, she would change out of her school shoes and into her size 8 pink Adidas Falcon W cleats once her school day finished, and worked out at the gym of her private, all-girls high school.) On game nights (Tuesdays), she would change out of her entire school uniform and into her football uniform immediately after the school day was over, and I would drive her to the local public high school, where she played her games.
