Watch 12 O'Clock High. Dad flew these big bombers and was interested. Have most of them and Combat shows in DVR. When I started watching there were two networks NBC and CBS. Then ABC came along as the new station. We used to visit our Grandparents and beg to watch Bonanza before leaving not because we liked it, but because they had a color tv and it was in color. Going back to the tubes. The tv would go out and Dad would grab some he thought were bad and head to the drug store where there was a tube tester. Find the bad one, buy a new one, go home and plug it in and we were back in business. Good memories.
