Yard Sale Treasure Map - A Yard Sale Planning Tool

Yard sales by city. I'm more a fan of the idea of a yard sale map than a yard sale in general. I wish could find old Eames chairs and other midcentury modern furniture at yard sales.

I could find many other uses for similar maps: cupcakes, veggie food, restaurants open after 10 pm on weeknights, stores that carry iron on letters...If only more things were searchable in conjunction with maps...
