I like Bill Heavey on the back page of Field and Stream, especially the one about bowhunting in the median strips around his neighborhood. (ok, not really gun related but a bow is close enough) also, Stephen Hunter. If you can get hold of "Sportsman's Notebook" by the late H.G.Tapply there is a lot of good stuff regarding hunting, general outdoor skills and fishing. Mas of course. Jeff Cooper's stuff, if I ever need it, I am sure I will appreciate his emphasis on speed and violence of action. It sounds kind of like USMC war fighting doctrine only on an individual scale.
