Aldo Leopold - A Standard of Change is a one-man, one-act play written by and starring Jim Pfitzer, and directed by Trish Wileman.

Set in one evening in and around the famous Wisconsin Shack that inspired much of his writing, A Standard of Change explores the influences and challenges that led Aldo Leopold to penning his widely popular book A Sand County Almanac.

As the lights come up, Leopold walks up the path. It has been 64 years since his death, and as many years since he has seen his now historic Shack. Awaiting him are surprises, memories, emotions, and stories to be shared. Leopold invites his audience to join him as he reacquaints himself with his beloved landscape, remembers influential friends and family, quotes from some of his most important writings, and ponders his legacy.
