Perry was my graduate advisor in the early 1980´s. He was a great guy and a friend. We shared a love of the outdoors, hydrogeology, canoeing, trout fishing, and we are both Eagle Scouts. He kept tabs with me over my whole career. What a great man! He was extremely proud of his family. And he loved his property up in Hill City. Professor, author Peace Corps alumnus, Eagle Scout. His influence on his students is profound and lasting. I am a much better person because of Perry Rahn.
