I answered a Craigslist post and ended up getting several thousand free cards from a guy in Brooklyn. There was too much for me to carry on the subway, so he was kind enough to let me go through boxes of cards in the foyer of his brownstone for half an hour. He still has about 10,000 cards left to give away - mostly "junk wax" (some of which were possibly complete sets of 86 Topps, 87 Topps, 88 Donruss, definitely complete 89, 90 and 91 Topps Traded) but there was a lot of vintage baseball and football which I don't touch because every collection has got to have some limits. I even saw stuff like '75 Topps Mini and '77 Topps Cloth. His apartment is a block away from the R train so easy to get to for a New Yorker (like Night Owl, for example). If you want to get the rest of the cards, here's the link to his Craigslist post - tell him Bo sent you!
As for what I got, here are some highlights:
A ton of 1992 Leaf, both regular and Black Gold. There will be a lot to trade from both, like this Black Gold Rickey, of which there were at least two.
Ames Fan Club with interesting forums about Ames and other defunct retailers, and the traces you can find of them today. Interesting stuff.
