The destination."This is going to be so cool" Claims my traveling companion,Rupert, exclaims after hearing my decision to go with him.Forty years ago I remember that same voice more youthful,steady, at The Naval Hospital,Great Lakes,Illinois where we met working as hospital corpsmen-5-north psychiatric unit(closed ward). I was trained @ The US Naval Hospital,Philadelphia,Pa in the specialty for Neuro-psychiatric technician;Rupert fresh out of Hospital Corps School,still calling everybody "sir".
