I have paid quite a ways into future.  Been taking advantage when they offered keychains and decals etc.  Also my Dad died in August, this year and I had them in Texas  transfer remainder of his subscription to mine as I was paying for his anyway.  He had maybe 3 issues left on his subscription/membership when he passed away.
I also have the equalizer pedal put on '46 60 tractor, works good.  Thanks, Terry
