What is your most memorable NES find in the wild? Finding a rare game? Finding a game you wanted to own but couldn't find anywhere? Coming across a bunch of games in a thrift store/pawn shop/yard sale/etc. for next to nothing? Something else? Tell us about it! If you've got a story, share it, and if you've got pics, share them!
For me, I don't have an NES in my collection yet (although I want to own one someday) so my find isn't that impressive - it was a loose cart of Stack Up for $7.99 at a Game Crazy. A friend of mine had just bought a ROB off of ebay and was interested in getting the game. I was at that Game Crazy the day before and remembered that I saw Stack-Up there, so I told him about it and he told me to get it and he'd pay me back, so I went back the next day and bought it.
