To use the facilities, you need to show a valid Clark ONECARD to the proctor on duty and sign in for security purposes. You may bring one guest with your ONECARD or family pass, when using the pool, racquetball courts, or general gym area. When entering with a guest, you must leave your ONECARD with the Proctor when signing in and pick it up on your way out. Your guest should remain with you at all times, and is expected to leave with you.
