I knew Ruth Johnson personally. She was a nurse anesthetist at Port Huron Hospital where I worked as an RN for 25 years. I bought her magazines, too.
She did a great thing with the magazine...too bad it changed so much when she retired from it. I may have met her at a seminar I went to in Sarnia WAY back. It's too bad also that the Bluewater Machine Knitters group dwindled down to only a few.
