IIRC 1962 to around 2002. The Amateur Scientist with Forest Mims III was good but he got hounded out because he wasn’t an evolutionist. Shawn Carlson took it over and had some good stuff but it was put to rest in 2002. After around 1992 I don’t think I read any of the feature articles in the magazine. For the past 15 or so years, I haven’t even bothered to thumb though one at the magazine stand. Looking at a cover is enough. Sad.
When Rennie came in, it sealed it for me!
