Good grief, you had to ask. I'm a reader, so without making a comprehensive list, here goes:
GRM and Classic Motorsports, Road & Track, Racer, Corvette, Vette, Hemmings Classic, Old Cars Weekly, and Hagarty for car mags (a friend gives me his copies of Racecar Engineering); Analog SF and Hitchcock's Mystery Mag for fiction; The Writer and Writer's Digest; New Mexico magazine, Arizona Highways, Colorado Outdoors, Scottish Life and The Highlander (Aye!), True West and Wild West (I write for WW), Western Horseman, with memberships I get Western Writers of America's Roundup and the Wild West History Association's Journal. Probably a couple more that don't leap to mind right now.
