During Divorce #2 I was so glad I had the then past 15 years of records etc in bankers boxes. Those were the higher income and spending years and it helped my case a lot. Then after she got the house and I moved, I hauled a truck load (not kidding) of paper over to a commercial shredding outfit. Now I keep the current year plus the past 7 and anything older is shredded or burned.
And I did find a couple of old circa '92-93 DVD's of some porn skits. One was some kind of a game that I never played just went right to the avi files. Lots of the old time porn stars in there. Also some college dude that specialized in picking up coeds taking them back to his 'studio' and having them fuck his brains out while he recorded them. Good stuff back then, had more of a real feel to it even though it was mostly staged.
