Until clearly evident that rigid supervision is no longer needed, each cooperative area will have at least one supervisory officer, temporary or otherwise, appointed by the Director, on duty at a conveniently located telephone on or adjacent to the area. All participating farmers will be informed of the location and telephone number of the officer. These facts are to be posted at each parking area to inform hunters or other interested parties. Check in stations may be located with the supervisory officer, and the station may be used to control the number of hunters on any Cooperative Area and to collect a nominal fee for operation of the area.
