Admiral Yamamoto infamously said "You cannot invade the mainland United States. There would be a man with a rifle behind every blade of grass."
And so it should be, a nation of riflemen....
I feel the pain. My Dad would have been 100 next month. We lost him in 1982 - too young to die IMHO. He taught me to build a crystal set when I was 9. Toilet paper roll coil, gallium arsenide catwhisker crystal and a set of old USN headphones he had. Lousy bandwidth, but I loved it and listened to it every night going to sleep. Still miss him.
Lost my Dad in 1988. He would have been 108 this year. I think of him all the time. What is sad is that there are fewer and fewer people who I can share stories of my Dad with.
Lost my dad in 2011; still keep thinking of things I'd like to ask him about. It's said that every time an old person dies, it's like a library burning down.Some not so old people, too. May your memories of your dad be only good ones.
Sorry for your loss.
Keep it civil, please....
