I have two yards close to me , one You almost have to pay them if You bring in " white metal " and tries to screw you on everything else .
The other one , owned by a friend I grew up with ( great when I need a part ) use to sort and weigh everything separately , with a attendant , but now has You just drive over the scale , and dump in one big pile and they pay a flat rate , last week $ 230. a ton , Cars , brake rotors and drums , washer and dryer, aluminum , Rocks
, etc. I use them for quick cash or to clean out a trailer .
We have another place that weighs everything separately , copper , alum. , # 1 , #2 steel , and pays a LOT more but they are 60 min. away and You always have to wait in line .
