This is true in my case as well. I very rarely drive around houses looking for scrap, only time is if it's trash day and I'm around there already. I specifically target "low income" apartment complex dumpsters etc and I do well. I don't dumpster dive but most of the time I get plenty from right around the dumpster. Another thing to add is that the appliances (stove, fridge, washer, dryer, air conditioner, ceiling fan) don't belong to them most people really don't care what condition they keep them in, one complex I frequent I found 3 electric stoves by the dumpster in a weeks time.
