Your math is slightly off. He would have been 18 in 1979, as he is one year younger than I am. All males born after December 31, 1959 are required by law to register with Selective Service. It is a felony, IIRC, to fail to do so.
Oh sorry my math is off...
I was just pointing out that the SS was still in effect then...
I dont know if he registered but wouldnt he have to ???
