I used to subscribe to a bunch of mags...sign up for one year, and get extended almost indefinitely...7 years of ESPN. Now that I don't have a US address, no more kindling.
Mostly car mags, and a few science and tech ones. Somehow got Working Mother for a couple years...never asked for it, and I was a stay at home dad (but started getting it just before wife got pregnant). Hockey Digest turned in Football digest thanks to the lockout.
Edit: I did sub to Playboy when I was active duty USMC. I never got to open it myself though...by the time I got to mail call, the plastic wrapper was always long gone.
