AM - Winslow Tunnel
Posted August 22, 2019, by Sandra Pense Lynch (moomule [at] aol [dot] com)

My grandfather, Robert Pense of Winslow , Arkanasas, helped build the Winslow Tunnel. He was renowed in his community for his skill with an ax. My dad, Carl Pense, started jumping on the train in the tunnel at the age of about 12, riding to another community and buying a horse and small herd of cattle and taking them back to Winslow to sell. He moved to Illinois as a young man and became a successful farmer and livestock dealer, in spite of the fact that he never learned to read or write. Dad was killed in a truck accident in 1989 at the age of 72.
