He wrote this poem:

"I've walked on the Arctic IceCap and on the shores of the Phillipine Sea, Been to Nan-Madol and the Costa del Sol, Seen all that I could see, been to Saipan, Jaypan, Vietnam, Malmo, Olongopo, and Sasebo, Hongkong, Saigon, and Kobenhavn. I've walked I the Black Forest of Germany, strolled thru the Gardens of Tivoli, watched the Fire Fall in the Valley of Yosemite, and saw the tulips in bloom on the Eider Dee". ~ by: Denver Cogburn
