That's an awesome idea and if I get the chance, I will do it. I certainly have the technical skills and I am uncannily good at going about unnoticed.
My mom confessed to me when I shared my doubts with her that she left for about a year in the late seventies, but she didn't specify why; only said that she had doubts as well. When I learned about the '75 fiasco it was the proverbial light bulb going off in my brain. Before then I had always assumed that she had been stumbled by some other witness, but now I know that she knows the GB is fallible.. and chose to come crawling back to them anyways. The strange thing is that I don't think she did it over shunning; she really seems to believe the WT theology even though she knows they were wrong.
