I found literally a full bedroom of oak furniture, bed, a dresser, a desk, a bedside table, and an armoure... I could not get the armoure on my pickup truck, but I moved out all my old stuff, and moved in the oak, and oiled it all up, ( it had not been cared for well, so it soaked up all the oil, after a few treatments, it was grand.
Literally every university town, Berkeley, SF State, Cal State Chico... has yard sales in the late spring, and resales in the early fall, and a literal cottage industry of people who make money reselling, and armies of people who drive those neibourhoods late a night picking up everything they think they can resell - Its why all those mattresses are left.
