Allan D. Walcker went to meet our Lord on July 15, 2022. He was born in Underwood, North Dakota, over 91 yrs ago. He joined the Air Force after high school and met his wife, Peggy, while stationed in Biloxi, Mississippi, on a blind date. They had three children, and upon retiring from the Air Force after 23 yrs, they settled in Cheyenne in the early 70s. He went to work at Wycon Chemical Co and retired after 22 years. He loved to travel around the U.S. with Peggy in their motorhome and enjoyed working on puzzles with his family. He is preceded in death by his wife, Peggy, and his parents, August and Sophia Walcker. He is survived by his children, David (Ginger) Walcker, Paul (Lori) Walcker, and Monica (Frank) Huereque; grandchildren, Jena (Ryan) McHugh, Adam (Summer) Walcker, Cheyenne, Nicole, and Ian Huereque; and four great grandchildren.
