Video Game Yard Sale... Treasures?

Just yesterday I went up to a yard sale, and was happy to find that they had some video games there.
They were all old crappy PC games, and I bought most of them since they were all a buck or less.
Among them are Silent Thunder: A-10 Tank Killer II, Microsoft Flight Simulator (the original from 1995), Goosebumps: Attack of the Mutant, Mortal Kombat II (for DOS!), and the newest one of the bunch... Wildlife Tycoon: Venture Africa.
It's been a while since I've gotten video games from a yard sale... hell it's been a while since i've WENT to a yard sale.  I remember back in the 90's finding Atari 2600's with whole sets of games for around 50 bucks, sometimes even cheaper.  I remember finding a whole case of NES games for 10 bucks.
It seems the age of Yard sales are dying down, now with the advent of Ebay, and people being able to generally get more money selling stuff online than off their front yard.
Do you guys have any good memories of yard sales gone by? remember finding any good deals on video games?
