Rdorman,
Those are the main shows that I watch. I have learned more from them than I did when I was in college. They had another one on about Yellowstone and what could happen if it erupts. I am a history buff and really enjoy watching the discovery and history channel shows. And they are finding new things every day it seems. I really enjoy the shows about the underground cities. Did you see the one about Hitler's underground Berlin?
