The best paragraph from SSS Form 7, Dec 72 [my Vietnam-era draft card]:

``Personal Appearance Before the Appeal Board -- may be requested if you are eligible to request an appeal to the appeal board. You may appeal to the appeal board without requesting a personal appearance before the appeal board, but if you wish to appear before the appeal board you must specifically ask for the appearance in addition to requesting the appeal.''

[Translation: GO AWAY!]
