October 7, 1998, on a picture-perfect day, David and Earl summited Mt. Katahdin together, surrounded by a cadre of hikers and friends.

David Shaffer

David W. Shaffer, nephew of Earl, has many memories of spending time with Earl on the trail.  As a youngster, helping Earl maintain the trail and hiking together helped develop my love for the outdoors.  I was lucky enough to be a small part of his 1965 hike as well as include my daughter as part of his 1998 50th anniversary hike.  I worked with my dad, John Shaffer, Earl and others in initial planning of the foundation.  I have also served as secretary.  I am the owner and operator of Superior Lock & Safe Co. in Pickerington, Ohio for the last 40 years.  When not busy with work, I enjoy spending time sharing my love for the outdoors with my grandchildren .
