Still findable?

In my quest for vintage pre-war cards, I'm finding it harder and harder to just find them at yard sales, estate sales, etc. Do any of you collect these and are you finding it hard to pick them up at sales? I've always loved the thrill of the chase in finding these cards, but it seems the only place you can find them are online auctions now.

eBay = sell to the world
flea market/antique mall = sell to the neighborhood
I think its an easy one to choose.
Been a long while since I've seen a good pre-war card around. Lots of 50s and later stuff still in the antique shops. But never priced according to the market. Always near mint to mint prices for excellent to poor cards.
