Hey cbgb
When I was in junior high my science teacher was in to UFO’s.
I became interested as well.
My favorite writer in the subject became John Keel.
Our Haunted Planet.
Operation Trojan Horse
Strange Creatures From Beyond Time and Space
Then Mothman Prophecies came out and, lastly, The Eighth Tower.
I ate them up.
Now I like to look at
I have fond memories of Keel.
