As a control line flyer back in the 1970s I never really thought too much of RCM, but got a few here and there as the ads were pretty good and they had some related stuff. In the 1990s I reread them all after going a bit more into RC, and of course the "For What It"s Worth" column is dog eared, and something is written on the front cover, and side if there was something in that column, or a plan or something interesting. Maybe I have over 100 magazines, not all RCM though.
