I first subscribed to SI around 1964. I let my subscription lapse around 1994 because of their left leaning ideology.
When they started on their Sierra Club kick around 1985 or so that was the beginning of the end. Up until then it was A great magazine. I hope all “right thinkers” stop subscribing.
I used to get it and the old newspaper type edition of the Sporting News in the 1960s. SI was turning into junk and I quit way back in the late 1970s. Not just left crap, but their mags were just getting boring.
