Opinion by JUDGE PIERCE Petitioners seek review of the award of workmen’s compensation benefits granted to respondent Maureen Hendricks-Rauch. We affirm. The facts of this case are essentially undisputed. Hendricks-Rauch was employed by the University of Colorado Medical Center to provide clinical consultation to rural nurses during approximately two weeks in the summer of 1977. The terms of the employment provided for Hendricks-Rauch to receive $100 a day plus expenses for her services. While traveling by bus in the course of this employment, Hendricks-Rauch was struck in the head by a suitcase falling from an overhead rack and suffered the injuries which are the subject to this claim.
