Nedra's health was failing and Don didn't spend much time at their home in Roswell, GA. This was largely ignored in the narrative or glossed over, but an impeccable source told me that Don was rarely " at home" in Roswell, GA, preferring Boulder because " Nedra was a difficult person in her ways. "
As we all are likely " difficult" to some people in some ways, I do not consider this an inflammatory or unusual statement for people in their age group. Her main problems were diabetes and diabetic neuropathy by the time this all occurred, so she was having problems with mobility and endocrine issues with glucose control, etc. I don't think she was able to do much walking or traveling at all. Source- her physician.
