(Wieczorek) Heiter; father of Rob (Tamika) Heiter; grandfather of R.J., Cameron, Trinity and Londyn; son of the late Hal and Shirley Heiter; son-in-law of the late Frank and Iris Wieczorek; loving brother of Robin J.

Bob was an avid hunter and fisherman. He loved the outdoors and always said he "felt closest to God in the woods". Having hiked many National Parks, he treasured the ones in Wyoming, Montana, Utah and Colorado. His favorite activity was elk hunting in the Rocky Mountains on horseback. His life was an adventure and moving frequently never phased him. The phrase "never met a stranger" was the perfect description of Bob. Most encounters would end with a big bear hug, whether you wanted one or not. He will be deeply missed by all who knew and loved him.
