Adventure Cycling (well, Bikecentennial!) member since 1975.
There's been many a cold, wet winter's night I walked over to the bookshelves and pulled out a 7 or 18 year old copy of Adventure Cyclist (or BikeReport!) and vicariously relived a tour with one of the old contributors.
I haven't been a steady member over that period but I too will review old issues of both magazine versions when I'm on a stationary trainer in the winter....and dream. It is the one magazine I keep and try to read in little chunks and savor during the long wait unil the next one comes in the mail. A good organization and part of the $40 is tax deductable I believe.
+1 on ClemY's suggestion of Backpacker magazine - especially their annual gear guide.
