Here in my city there used to be "Big Trash Day" - when you could take out any old crap you don't have time for a garage sale for. IT WAS FANTASTIC! And a much missed SF tradition of wondering around the neighborhood and collecting neat stuff, and often - depending on the neighborhood - have to compete with pro estate re-sellers out there for that occassional high dollar freebee. What-ever was left went in the dump - but I say 60% of it got picked up by your neighbors
e.g. My wife and I were out for coffee, and came across a nice peices of 40's arts and crafts that sold in consignment for $800. (<10%) The very next year scored a dresser that we use as a side-board - early 60's contemporary but very nice solid woodwork, full book-matched, blind dove-tails in blond maple - (I told the wife 'you sit here on this while I go get the van') still has the "free to good home" sign in one of the drawers.
Now the dump has stopped offering that big trash day - and you need to pay them to come, or pay "Got Junk" to come get it - who, it anything have any value that you did not realize will re-sell for additonal profit. And a tradition/street party/junk fair/trash gold mine is now gone....
As for copper - glad the prices are down. It's about time.... Much of that was due to a panic caused by some loud mouth in the goverment at a congressional hearing saying 50% of the worlds copper was tapped out, this coinciding with a strike at a mine in Chile - shot copper through the roof - I feel needlessly. That would be like our president saying, 'You everything to fear and loose - run on down to the bank and get your money out NOW! (Chuckle - chuckle)', as opposed to "there is nothing to fear, but fear itself"
As for wire theft - I have not lost any during any part of the last decade - other than my scraps getting cleared off the floor faster.
