For several years, Jim put huge effort into caring for his wife, Fair Anne (the Lady in the Sun, as he called her) as she went through a long, slow decline with cancer. My wife and I visited Jim and Anne at Christmass time, 2017, and she was struggling then; she lasted until just a few weeks ago. Two daughters were with him at the time, and stayed a couple of weeks afterwards.
Since Ann's passing, Jim has been on a frantic round of traveling, first up to PA to visit family there, then down to Houston to a wind power conference. From Houston, he flew to CO to work with a friend on siting a wind power project in the mountains; this took about 2 weeks, as I recall. While there, he purchased a used Volvo to drive home as he had accumulated a lot of stuff at garage sales (tools, TV, computer gear, etc). He sent me a photo of himself with the rear of the car open showing all his acquisitions filling the rear of the car. On the round was the small backpack containing everything he had started with on his travels. I last heard from Jim about 10 days ago. He was near Tulsa, visiting his sister, and planned to start back to Hardy, Arkansas the next day.
His friendship and knowledge will be sorely missed. I suspect that life without Anne just was not worth living for Jim.
